I bought ym truck in October of 2016 and at the time didnt appear to ave any bad rust but since then the rear right wheel well and fender have gotten much worse. Recently the paint bubbles have been peeling off and leaving bare metal exposed underneath. I got quotes from a couple body shops for the work but it seems like a lot of money. I got my bed line-x'd recently and went back to them to see if they could spray the wheel wells and spray fender flares onto the body a bit. I am wondering if removing the rust, priming and spraying line-x onto it will keep the rust out of my life for a few years or if it will just come back. Guy at Line-x said it would be fine and would work well but i'm looking for some other opinions before i spend this kind of money.
