I've looked at the avalanche forums, and other than complaining about their fading cladding (8 months after purchase its already light gray!) they don't say anything bad about the gatorback. It seems to really work. I'm pretty sure this will cover the gas stains and other cladding issues (PO glued a vanity plate to the front leaving four holes and some stains) as this seems paint like. I'll add this to my list of things to do when I have money.
