I've got a 2015 silverado and it's coming up on the time of year to go back in to the detail shop to have the truck re sprayed for the undercoat/rust proofing and have an interior detail done and have them detail the outside and respray the year round wax (diamond gloss). Every time i go in for something at my detail shop they usually try to push me to get their chip protection film installed. I turn it down because I don't see a need. 1 it's a pickup and while I want to take care of it as best as possible and want to avoid rust as much as I possibly can, it is going to go off road, it does have off-road tires, and I use it so naturally it does have and will get more chips. 2 With the chips that it does have, it has been through a couple full winters and I have seen no rust in the chips. If I ever did see any, I would immediately use a paint pen and scrub out the rust and fix it. I'm not going to inspect every square inch of the truck for this constantly but you know what I mean. My question is, do other people feel the same way about this or is it really a necessity if I don't want to have a rustbucket 10 years from now? I wash the truck usually every week and in the winter whenever it's warm. And like I said, if I saw a rusting paint chip it would get fixed. Any and all advice is appreciated. Thank you!
