I sparyed Duplicolor bedliner on my rockers about a month back and now it looks like crap. I was thinking about removing it but dont know a good way to go about it. Or should I just go over it with another brand like Rustoleum?

 

Aircraft stripper.

Take it down to bare metal, prime it, then line it. Use a real roll on bedliner, not the spray can crap.
