Rustproofing?
This warranty covers repair or replacement of any original body panel that develops perforation from corrosion (rust-through), subject to the exceptions listed in the Basic Warranty page. The Corrosion Perforation Warranty coverage is for 72 months, regardless of mileage.
I get all my cars (and family too) done every couple of years (even for the 'permanent' products). The product I use is called 'sym-tech' & it's a yellow paste type product that has been around for decades & improved during that time too.
I'll put it this way......I owned a 1991 Olds Delta 88 Brougham as my first car during the mid to late 90's....& did this religiously....I still see the car on the road from time to time & the body is in excellent condition. I just wish the current owner maintained it better lol.

Never get it done at the dealer.....they bend people over the barrel as it's a huge profit for them ($1,000+ for the 'package' is not uncommon). I pay cash under the table at the shop I use & save close to 80%.

I've heard many arguements from actual dealers sales staff that tell you never to have this done (and it might even void the factory warranty!).....as soon as I get in the 'business office' to buy the car, it's one of the first things they try to sell me (after that extended warranty).
