waxing every week does not prevent clear coat failure? dull clearcoat = impending failure?

Where I live is like Florida, but with less humidity. What I found out is that darker colors take heavier toll regarding clearcoat failure. Most of cars that come to my shop with clearcoat failure are dark, especially black, dark grey, blue etc. I have a fifteen year old metallic silver car with no sign of cc failure, although the cc is a bit thin.
I coat my car every 18 months, and after a wash I always apply a sealant/wax/liquid wax, since I use my car as a testing ground for new AG products.
White cars get impregnated with dirt after couple years, giving a brownish look (my wife has a white car).
IMHO, silver is the best color for heavy sun exposition in the long run. By long run, I mean 10 years or more.
All the best
 


Optimum Spray Wax has 2 patent UV protection.



And I share this information on page 2 of my article below including a picture of the chemist himself that develpoed the product.

I think I already included the link to this article in a previous post to this thread but I also know people are scanners and some won't click on a link and read but the info is there.

That's correct, here's why in an article I wrote back in 2012

Here's as two articles on the topic of how paint gets dirty. In fact, this first article explains that it's NOT just white cars it's just the human eyes really only see it on white cars. The reality is it happens to ALL cars and this is why you don't want to LAYER waxes or you'll layer in the dirt. I actually posted about this somewhere else on the forum yesterday.


First article - Written back in 1997 - almost 20 years ago...

And here's yet another article on the topic of dirt stained paint

Dirt in Paint or DIP - Stained Paint - Dirt Embedded Paint


And another article...

How to remove stains and embedded dirt out of paint


DIP = Dirt in Paint
Here's a shot of one of our used pads next to a brand new, never before used white polishing pad. This color transfer from the paint to the pad is a type of dirt staining that build-up on the finish and comes off when you're machine polishing.

Actually, I'd say the best paint type and paint color choice for longevity in a harsh sun environment would be white single stage paint.

The pigment for white paint is titanium dioxide and it's a very hard mineral that creates a very had paint that resists corrosion and degradation. This is one reason most airplanes and jets are painted with single stage white paint. Who wants to pay to have a plain or jet repainted?

Single stage paints oxidize and you can fix oxidation. Basecoat/clearcoat paints fail, that is the clear layer disintegrates and flakes off. You and I cannot fix clearcoat failure unless we have the ability to repaint our car.
