Me and my father in-law bought new GM trucks,both are black and he had the dealer put some perma seal or something on his, he gets this put on all his new vehicles that he swears by and i didn't get it put on mine. What can i do myself when i pick up my truck, to have something as good as what he got?I'm new to waxing, never have done much of it..thanks a lot
