I'm taking the rust and old primer off my truck via sanding with a random orbital sander. There are a million little areas like little ding marks that still have spots of rust in them. Is an etch primer good enough or should I treat it with something?
There are some big areas like the rear fenders that were covered in rust. These I lightly ground down with a 3m pad , dusted the debrie off, washed off, then applied one step from mar-hyde which converts rust to black primer.
This process won't work fo the mostly bare metal with rust dots though. I'm looking for something I can apply and primer over the same day. Any ideas?
When I'm done it still will be 6months - year before the finish painting can happen. So on that note any primer that with prevent new rust? Thanks, Steve.
