It does not say on the website, whether it has a UV protectant, but it is totally endorsed by GM. The dark grey is probably closer to O.G. look, but i figured the black would match my wheels better.....
Go on their site, it is very informative. there is a cladding resto section, aswell as a section on other protectants that they offer.
in the cladding section, there is an actual GM downloadable document, stating that gatorback provides extra longevity and fade resistance for cladding.
