Does anyone know how quickly a wax like Meguiar's Gold Class breaks down when exposed to direct heat/sunlight? I have heard you can spend hours waxing your car, but then just one afternoon sitting in 100 degree heat and much of the wax has evaporated or melted. Is this true?? One source i read cllaimed that carnauba actually gets sticky in extreme heat and will allow dirt and dust to adhere to it. I have also heard washing with very hot water will do the same thing -- break down the wax and undo your hard work.

I have heard of high-temp waxes and waxes that specifically protect from UV rays... but actually how heat-resistant ARE your average (or above-average) carnauba waxes (meguiars, zymol, etc)? do you really need to re-wax every 2 weeks (as some sources claim) if you car sees a lot of texas sun?

I don't know this first hand, but I heard Collinite C476S DoubleWax works well at high temperatures and is quite long lasting...

Have a friend who coats his wheels with it and swears it lasts and lasts. :dunno I'm gonna try it out...

Bought mine from www.waxbytes.com.

It all depends on the wax. Not all carnuba waxes are created equally. Some may have more solvents in them to make them easier to apply, but the durability is adversely affected by this. Others may have more oils to give a better shine, but they too will last less time.

Pinnacle souvern is highly regarded by detailing enthusiasts to be THE best wax on the market for shine on dark colours. The problem is it will only last 2 weeks in the best of conditions.

Pinnacle paste glaz is highly regarded by detailing enthusiasts to be THE best wax on the market for shine on light colours. It too will only last 2 weeks in the best of conditions.

Blitz wax by One Grand (what I use) is regarded by most detailing enthusiasts to be the best wax for daily drivers because it gives the best shine next to pinnacle but it will last for three months in the most ideal conditions. I can personally attest to this.

As for your carnuba getting sticky, not likely. The layer of carnuba wax on your car is 1mm thick. If it ever melted, you wouldn't feel it. No serious dirt would stick to this either. Dust yes, dirt no.

Most high temp CARNUBA waxes are a sham. The only thing more durable than carnuba is synthetic sealants like klasse and zaino.

As for zymol, save your money. The stuff sold in pep boys etc is actually repackaged turtle wax. The online stuff isn't worth the money. There is NO way that zymol or meguiars will outlast or outshine blitz.

Are you really set on a carnuba wax? Carnubas protective properties become unstable at about 190 degrees I think, so if you live somewhere really where the car sees 100+ regularly, you may consider switching to a acrylic based solution like Klasse. I am not a big fan of Klasse in particular, but I am using some stuff from Classic Motoring that is called Blackfire that came out recently that remains stable up to 590 degrees! It has great depth of shine, brings out the color and my paint has NEVER been so smooth, its like polished glass. I highly recommend looking into it.

Here is your answer. I was stationed in Kuwait where temps run above 140 degrees in the summer, and the only wax recommended by BMW and Mercedes Benz, stood up to the test. I put it on, and my car sat in the sun all day, and after 2 months it still looked new. It protected it against the sun and the occasional sand storm. This is why, now that I am home and have a new M3 I use P21S. Also the guys at A and M Motor Sport who are BMW experts, and carry a number of waxes only recommend P21S products for BMWs. P21s Is OEM supplier to BMW, Mercedes, Mclaren, Porsche, Astin Martin and Porsche. I have seen their manufacturing and R and D facilities. It is all first class. They have new Mercedes Sls and Turbo Porsches and Z8s and M5s and M3sand the new Astin Martin all in the R and D department being tested and evaluated for new products. This is why BMW and others recommend P21S and not some others that do not even have an R and D department nor their own manufacturing capabiliteis.These guys develop and manufactuer car care products. They are Scientists and Engineers who know what they have to develop. If you have any questions about car care I would suggest www.aandmmotorsport.com

Thanks for the input, Madman... Do you think it useful to put P21S on my wheels? (already use it on the body).

I currently use Klasse All-in-one and Klasse sealant Glaze on the wheels.

In your experience, would P21S stand up to the heat of wheels as well as help them shed brake dust? or is it an exersize in futility?

I use the P21S cleaner then follow it with wax but first I use P21S High performance wheel cleaner it cleans the wheels of any residue and brake dust, once that is done the surface is ready for the paint cleaner and then the wax. Rewax your wheels again in 4 to 6 hours to give it long term protection, I do that and now 3 weeks later all I do is just hose the wheels off with water every 2 to 3 days and wipe dry the wheels stay nice and new. Now a good side effect is that it gives your wheel a hard protecting surface. I found that by doing that I avoid little nicks and chips off my wheels The wheels look as good as they did when I picked up the car at the dealer.

Forget Collinite on wheels. Seems to attract brake dust! Could not rinse off dust easily. :az:

Removed with Klasse All-In-one and 3 coats of Klasse Sealant Glaze. Klasse withstands the heat of the wheels, lasts, seems to shed brake dusts, and is very easy to clean.

No info on how the collinite holds up on the body. I think Klasse polymer/Acrylics are best for extreme heat.:atom
