Priming my inner fender liners w/ rustoleum auto primer and the finish came out really rough, like sand paper. The fender liner was pretty smooth prior to being sprayed. From what I’ve read, sounds like it came out too dry? It was a new can, but it’s been in my garage for a few weeks. Is this normal, or is it just rustoleum? A friend who restores C1 corvettes prefers krylon. Thoughts?
