I trashed the White Diamond Paint on my brand-new, 3-day old 2005 Escalade.
I put on "Black Magic Tire wet gel" on the tires. DO NOT USE THIS PRODUCT! Its a gel to shine the tires and after you put it on, you let it sit for 10 min so it can dry and not spin off. Well no matter what, it will spin off. And wherever the spinoff goes, it turns the white diamond paint a dark yellow, perminantly. This stuff sucks! The tires look fantastic but the pain is distroyed. I tried compound, wax, everything. All the spray up went on the bottom part of the doors behind each tire and the backs of the painted mirrors.
Here is the website so you can see what this crap looks like so you can avoid it. I bought it at pepboys.
