I used Duplicolor Spray on Bedliner. I chose that one because it seemed to have the most good reviews. Being a spray my thought was "touch ups" would be easier. The rear bumper just got sanded for the most part. Some grinding was done for the rusty sections. As for the front bumper, that's a different story. It was really rusty. I pretty much stripped it completely before painting it. I did not use any primer (directions said not to) and did many coats.
My only real recommendation would be to practice first. If I had it to do over, I would take a smaller used part and completely paint it to practice.
Good luck.

Lol thanks, I went back and read threw and realized you had said that, my bad! I really do like that bedliner just so far I haven't done anything other then the wheels on my truck but trust me that stuff is hard to take off unless you use a grinder or a rock. For just a simple cheap rattle can it is great stuff!
