Collinite 845 vs 915

Insulator Wax against Marque D'Elegance. Collinite publishes months AND square feet for both, which makes this the rare wax comparison you settle with arithmetic - and the arithmetic says the expensive one is not the durable one.

The verdict

Buy 845 unless your paint is dark, in which case 915 earns its premium.And if what you actually want is the longest-lasting Collinite, buy neither — 476S publishes a longer durability rating than both and costs less than 915.

That is an unusual thing to be able to say with confidence about two waxes, and it is only possible because of what Collinite does that almost nobody else in car care does: it publishes a durability figure in months and an average spread in square feet for every product in the line. Across this entire site, “lasts up to six months” is normally an adjective. Here it is a number you can line up.

The published figures, side by side

Every figure in this table is from Collinite’s own product pages, read on the dates in the sources below. The 476S column is included because it changes the answer.

The one number that surprises people

Look at the spread row again. 915 is the only Collinite that publishes a higher coverage range than the rest of the line— 1,400–2,200 sq ft against 1,200–2,000 — and it does it from the smallest container of the three. A 12 fl oz tin covering more than a 16 fl oz bottle is not what a buyer expects from the expensive product.

There is a plausible reason, and we will label it as our reading rather than Collinite’s: a paste is applied by loading an applicator from the surface of the tin, which wastes less than pouring a thin liquid, and “minimal buffing required” suggests a formula designed to go on sparse. Collinite does not say that. What it does say, on the Amazon listing, is the thing that makes the arithmetic concrete: “a single 12 fl. oz container can cover up to 20 mid-sized vehicles.”

That is the only vehicle-count figure published anywhere in the Collinite range, which is why 915 is the one product in this comparison with a live cost-per-car figure in the table above. Treat “up to 20” as a best case. Even halved, the per-car cost of a concours paste wax lands somewhere between trivial and irrelevant — which means price per tin is a bad reason to choose between these two, and the form and the gloss character are good ones.

Why 845 is still the default

One reason, and it is not price: Collinite tells you how to machine it. Its FAQ calls 845 the company’s most “machine friendly” automotive wax, says “A finishing pad and low speed are optimal in order to obtain professional results”, and states that the best results and spread were found with a DA. The product page adds “Best results/spread found by DA” and, for hand application, “a thin layer is recommended to one section at a time”.

No other wax on this site gets that treatment from its maker. For 915 and 476S, Collinite says “For Hand & DA Use” and stops — no pad type, no speed range. So if you own a dual-action polisher, 845 is the one product in the range where you are following the manufacturer instead of guessing. On a car that gets waxed twice a year, that is worth more than two or three months of extra rating.

The 12-hour coat interval is the other piece of 845-specific guidance worth knowing: Collinite asks you to “wait a minimum of 12 hours between coats to allow the product to fully cure”. If you were planning to double-coat a car in an afternoon, plan again — and note that neither 915 nor 476S publishes an interval at all, so for those two there is no stated answer.

When 915 is worth the premium

One situation, stated narrowly: dark paint you look at. Collinite describes 915 as its “highest amount of rare carnauba” and its FAQ says it is “specifically formulated to provide a deeper show room shine to darker colored” finishes. The Amazon listing adds that the carnauba is “#1 grade” and credits it with “adding reflective depth to the paint finish”.

That matters because carnauba and polymer do different things to how light leaves a panel. Chemical Guys’ own explainer puts it plainly: natural carnauba gives a warm, deep gloss and needs more frequent reapplication, while engineered synthetic protection bonds and lasts longer. Collinite is unusual in making both in the same line, and 915 is the carnauba end of it with enough polymer to still carry a 6–9 month rating.

Two caveats before you spend the extra. Wax fills nothing.On black paint, the defect that destroys depth is swirl marks, and no carnauba hides them — it makes them wetter and more visible. Correct first, with the swirl removal method, then wax. And Collinite itself suggests topping it: the FAQ recommends following 915 with S-845 Speed Wax for added shine and durability. A maker recommending a second product over its show wax is the clearest signal available that 915 is a looks purchase.

What Collinite does not publish for either

The data here is unusually good by the standards of this category and it still stops well short of complete. For both 845 and 915, Collinite publishes:

  • No test method behind any durability figure.No climate, no wash frequency, no panel orientation, no coat count. “6–9 months” is a rating on an undisclosed basis.
  • No total cure time. 845 gets a 12-hour minimum between coats; neither product gets a figure for when the protection is fully formed.
  • No application temperature range.845’s page notes its viscosity thickens in cold and thins in heat with no stated performance change, which is as close as the line comes.
  • No maximum coat count, and no carnauba percentage or grade on the maker’s own page for 915 — “highest amount” is relative to the rest of the line, not a number.
  • No numeric comparison between products.Collinite ranks its own range by “degree of durability” and by months, and never publishes a side-by-side it stands behind. The table above is ours, assembled from three separate product pages.

None of that makes the figures useless — a maker rating with no method is still better than the adjective most brands offer. It does mean you should read 4–7 and 6–9 as a published ordering rather than a promise about your driveway.

Collinite No. 845 Insulator Wax

The longevity pick. This carnauba-and-polymer liquid is the one enthusiasts reach for when they want a wax to survive months and seasons rather than weeks. It trades a little of the warm carnauba glow and some application ease for genuinely long-lasting beading.

Who it is for:almost everybody, and especially anyone who owns a dual-action polisher. Collinite’s own FAQ calls 845 its most “machine friendly”automotive wax and goes further than any other product in the line on method: “A finishing pad and low speed are optimal in order to obtain professional results”, and “Best results/spread found by DA”.

The published figures: 4–7 months of weather protection, 1,200–2,000 sq ftaverage spread, 16 fl oz, a “Carnauba-Polymer Hybrid Paint Sealant”. It is sold in one size only, and it sits in a lower price band than 915.

Honest cons: it is a thin liquid that must go on very thin and even or it fights you at removal, it carries the shortest durability rating of the three Collinites here, and its viscosity changes with temperature — thicker in the cold, thinner in heat — with no stated performance change either way.

Strengths

  • A reputation for real durability — well past a typical carnauba's few weeks
  • Strong water beading and sheeting
  • A 16 oz bottle waxes many cars, so the cost-per-coat is tiny

Trade-offs

  • The thin liquid must be applied in a very thin, even coat to buff off cleanly
  • Less of the deep warm 'glow' than a dedicated show wax

#2Buy this one for dark paint

Collinite No. 915 Marque D'Elegance Wax

Collinite's show wax, and the only entry in the line whose listing puts a vehicle count on a container: up to 20 mid-size cars from 12 fl oz. It is the one to buy if your paint is dark and you want carnauba depth without dropping to a six-week wax — but it is also the most expensive way to buy Collinite durability, because 476S publishes a longer rating for less money.

Cost per car≈ $1.99based on ~20 cars per unit at the current price (as of November 12, 2026)

Who it is for: black, dark gray, dark blue or dark red paint that you want to look deeprather than just protected, on a car you enjoy looking at. Collinite describes 915 as its “highest amount of rare carnauba” and states in its FAQ that it is “specifically formulated to provide a deeper show room shine to darker colored” finishes.

The published figures beat 845 on both axes that matter: 6–9 months of weather protection against 4–7, and 1,400–2,200 sq ftof average spread against 1,200–2,000 — out of a smaller, 12 fl oz container. Its Amazon listing is the only place in the whole Collinite line that puts a vehicle count on a container: up to 20 mid-size vehicles.

Honest cons, and there are three. It is the most expensive Collinite per container while 476S publishes a longer durability rating for less money. It is a paste, so it is more work than the 845 liquid. And its Amazon listing publishes no months figure at all — the 6–9 month rating lives on Collinite’s own site, which is why our spec row for it reads “Not published”.

Strengths

  • Listing states up to 20 mid-size vehicles per 12 fl oz container, which makes the per-car cost arithmetic rather than opinion
  • Rated for hand or DA use, so it suits a machine owner as well as a hand waxer
  • Collinite's own page calls it the line's highest carnauba concentration and formulates it for darker colors

Trade-offs

  • The priciest Collinite per container, while 476S publishes a LONGER durability rating for less
  • A paste, so it is more work than the 845 liquid - and Collinite recommends testing an inconspicuous area first
  • The Amazon listing publishes no durability figure in months at all; the 6-9 month rating is on Collinite's own site, not here

#3Buy this one for maximum months

Collinite 476S Super Doublecoat Wax

A carnauba-plus-polymer paste with a reputation for surviving winters that strip other products off. It is the durability answer for anyone who parks outside in a harsh climate and is not interested in reapplying every six weeks.

Who it is for: a car that lives outside through a real winter, where the question is survival rather than depth. This is the quiet answer that ruins the 845-vs-915 decision for a lot of people, so we are putting it in front of you rather than at the bottom of the page.

Collinite publishes 7–10 monthsfor 476S — the “highest degree of durability” in the line and the “highest concentration of polymer protection” — from the same 1,200–2,000 sq ft spread, in 9 and 18 fl oz, and recommends it as a winter wax. It costs less per container than 915.

The trade is gloss character and effort. 476S is a traditional hard paste worked in 2 x 2 ft sections and removed at haze, which Collinite says “typically” takes 1–3 minutes. It is a durability product, not a show product. Our 845 vs 476S comparison goes through that pair in full, and 915 vs 476Sputs the two pastes directly against each other — the comparison with no form confound in it.

Strengths

  • Carnauba and polymer blend - warmth of a wax with sealant durability
  • Long-standing reputation for surviving salt and harsh weather
  • A tin lasts an extremely long time

Trade-offs

  • Paste application is more work than a spray or liquid
  • Needs to be applied very thin or removal becomes a chore

#4Buy this if you want show gloss without a paste

Griot's Garage Best of Show Wax

A carnauba-packed wax built for looks. It lays down the deep, warm, liquid-gloss finish show cars are waxed with, especially on dark paint. You'll reapply it more often than a synthetic, but nothing else here matches it for pure depth.

Who it is for: someone who wants the deep-gloss look 915 is sold on but does not want to work a paste around a whole car, and is willing to re-apply more often to avoid it.

It is the comparison’s honest outside option rather than a rival on paper, because Griot’s publishes neither a durability rating in months nor a coverage figure for it — which is precisely what makes the Collinite line unusual. Decide this one on convenience, and decide the Collinites on their numbers.

Strengths

  • Rich, carnauba-heavy shine with real depth
  • Soft and easy to spread in a thin coat by hand or machine
  • Griot's quality and lifetime-support reputation

Trade-offs

  • Carnauba means weeks of protection, not months
  • A looks-first wax you'll top up often
  • Pricier than the everyday liquid waxes

Which one, in one line each

  • You own a DA polisher: 845. No other wax in the line gets pad and speed guidance from its own maker.
  • Your car is black or dark and you look at it: 915, and accept that you are paying for carnauba depth rather than months.
  • Your car sleeps outside through salt and snow: 476S, which publishes more months than either of them and costs less than 915.
  • You wax twice a year and hate pastes: 845, every time.
  • You want the cheapest correct answer:845 in 16 fl oz — one size to choose, the easiest application, and well under the 915 price. 476S sits in the same bracket if you would rather have the months than the machine guidance.

What neither of them is

Neither is a ceramic coating, and 915’s listing is unusually direct about the difference: it claims 915 “uniquely bonds to surfaces without the pre-requirement for paint to be 100% ‘surgically’ clean (unlike ceramic coatings)”. That is a real and underrated advantage of wax — the prep bar is lower, the failure mode is milder, and a mistake buffs off — but it is also the whole reason a coating lasts years where a wax lasts months. Our ceramic coating vs wax comparison sets out that trade, and is ceramic coating worth it does the money version.

And neither replaces the step before them. Wax over bonded fallout and tar locks the contamination under a layer you then have to strip. Collinite asks for clean, cool paint; the way you get it is a wash followed by a clay bar or an iron remover, which is the whole point of paint decontamination.

A note on safety. Both of these are applied to clean, cool, shaded paint, and both are thin-coat products — Collinite says so for 845 and advises testing an inconspicuous area first for 915. A thick coat of either is harder to remove than a thin one and does not last longer. Collinite also asks for a minimum of 12 hours between coats of 845 to let it cure. Wax over bonded contamination seals the contamination in, so decontaminate first.

Frequently asked questions

Is Collinite 915 better than 845?

On the two figures Collinite publishes, yes - and it is not the one to buy for most people. 915 is rated 6-9 months against 845's 4-7, and its average spread is 1,400-2,200 sq ft against 845's 1,200-2,000, from a smaller 12 fl oz container. But 845 costs considerably less, comes in 16 fl oz, and is the only wax in the line Collinite gives machine guidance for - its FAQ calls 845 the most 'machine friendly' and recommends a finishing pad at low speed. So 915 is the better wax on paper and 845 is the better buy unless your paint is dark enough that carnauba depth is the reason you are shopping.

How long does Collinite 915 last?

Collinite publishes 6-9 months of weather protection and calls it the '2nd highest degree of durability' in its line, behind 476S at 7-10 months. What it does not publish is any test method behind that figure: no climate assumption, no wash frequency, no coat count, no temperature range. The Amazon listing is quieter still - it carries no months figure at all, only the claim that the product is 'durability-tested in everyday, FOUR SEASON driving conditions and non-garaged environments (not just controlled lab settings)'. Treat 6-9 months as a maker rating on an undisclosed basis, which is how we carry every durability claim on this site.

Is Collinite 915 a paste or a liquid?

A paste. Collinite's own navigation lists it as 'No. 915 - Marque D'Elegance Paste Wax', and it is rated for hand or DA application with 'minimal buffing required'. That is the practical difference from 845, which is a thin liquid. A paste is more controllable - it is harder to put on too much in one place - and it is more physical work across a whole car. If you have never waxed a car by hand before, the liquid is the gentler introduction.

How many cars will a bottle of Collinite 915 do?

Its Amazon listing is the only source in the Collinite range that answers this directly: 'a single 12 fl. oz container can cover up to 20 mid-sized vehicles.' Read 'up to' as what it is. Collinite's own product page gives an average spread of 1,400-2,200 sq ft instead, which is a more defensible figure and a harder one to picture. Either way the per-car cost of a premium paste wax is small - the expensive part of waxing is your Saturday, not the tin.

Can you use Collinite 915 with a dual-action polisher?

Yes. Collinite states 'For Hand & DA Use' for 915 as it does for 845 and 476S. The difference is how much it tells you: for 845 the FAQ names a finishing pad and low speed as optimal and says the best spread was found with a DA, while for 915 it publishes no pad type and no machine speed at all. So you can machine-apply it, and you will be choosing the pad and speed yourself. A soft finishing pad on a low setting is the conservative read across the line - see our guide to using a dual-action polisher for the method.

Should I use 845 and 915 together?

Collinite's own FAQ suggests something close to it: it recommends following 915 with S-845 Speed Wax 'for added shine and durability'. That is worth noticing, because it means the maker of a concours show wax recommends topping it with a second product - which tells you 915 is chosen for how it looks rather than for the durability ceiling. If you want one product rather than two, that is an argument for 845 or 476S. What Collinite does not publish anywhere is a cure or wait time between the two, so there is no stated interval we can pass on.

Which Collinite wax is best for black cars?

915, on the maker's own reasoning rather than ours: Collinite's FAQ says it is 'specifically formulated to provide a deeper show room shine to darker colored' finishes, and describes it as carrying the line's highest carnauba concentration. Carnauba is where the warm, wet-looking depth on dark paint comes from. The caveat is that depth only shows on paint that has been corrected - wax fills nothing, and swirls on black paint are the most visible defect in detailing. Fix the swirls first; see our wax picks for black cars and the swirl removal guide.

Why does our spec table say Collinite's durability is 'Not published'?

Because our product rows are read from the Amazon listing each product is sold on, and none of the three Collinite listings publishes a durability figure in months. The 4-7, 6-9 and 7-10 month ratings quoted throughout this page come from Collinite's own product pages, which we cite in the sources below. We deliberately do not copy a maker-site figure into a listing-sourced spec row, because then you could no longer tell which source a number came from. The tension is the honest state of the data, not an error.
