If you would like I know a company that does the Rustproofing with Warranty. They specialize in Rustproofing. They only do Rustproofing , Paint Protection, Fabric Protection & Tinting. At least do the Rustproofing. If you do all the services at the same time you will get a better deal. Just do not let the dealer know about where you have done it. It's ultimately up to you as I am just helping a fellow member. I do not want to post this in public as I might get flamed. As I know that there are some guys here who works for the dealership. Just let me know.
