Look up a product called Dr. Colorchip. There should be different levels of it. You probably only need three basic package. It’s not the cheapest but it’s arguably the best.
Yeah man ,lots of chipped up trucks ,especially on the front fenders, but everything we wash is aluminum and fiberglass, no rust. You definitely wanna get that truck cancer fixed before it spreads, they got chip paint pens and bottles of it with a nail polish applicator with rust killer added in.
I’m going to roll on rhino liner on my bottom of my GMC. Mine is chipping bad as well, even with fender flares. Price we pay to be DRP man…
