They want to charge you 500 bucks for something thats not more than a sealant that will last a few months maybe. A friend of mine has that on his silverado and it looks worse and more scratched and trashed than any other car around.. haha. So basically start off with the basics. Tell them not to TOUCH IT, wash it or barely take the plastic off because I guarantee if you let them wash it they will put swirls into the paint(just look at it in direct sunlight). Start off with the basics, good soft wash mitt, good car wash, two buckets with a
grit guard(to remove contaminants from the mitt by rinsing and wiping on it) and good
microfiber towels for anything thats gonna touch your paint. Then clay, polish, seal(wax, sealant) and maintain. If you dont mind a swirled up truck then use an old bath towel but trust me its not worth it. if you wanna learn more check out
