I decided to refinish my 21" excel, stripping off all the paint was easy with CITRISTIP and probably my first mistake. Now nice and clean, I wiped it down with acetone wearing vinyl gloves, the applied DUPLICOLOR acid etching primer, let dry per directions, then topcoat color and let dry. Looked great, chipped easily down to bare aluminum. Stripped again to bare metal, cleaned with acetone, primed and topcoated with RUSTOLEUM bedliner per instructions, looks really cool, sort of a powder coat finish. Didn't get as far as getting the grips back on and it was chipping,what am I doing wrong, I wish I left the original paint on and just painted over it. Acetone and primer are the common elements, don't know if they are the problem,should I go straight to bedliner and no primer? I've read some guys prime, some don't, anyone use Rustoleum bedliner spray?
