hey guys, awesome topic here
im from honda-tech, and have read all 40+ pages of it. my civic is coming along really nicely.

But, i am having an adhesion problem on one part. On my brand new bumper (polyurethane), i used the rustoleum auto primer spray, wetsand that then rattle-canned it. did 1 light coat, and left it alone for a week while i worked on the rest of the car. today, while i was hosing down the driveway, i decided to hose off the car, and the pressure from the hose completely stripped the paint off the bumper, and i can peel the paint off like a banana peel.

so the rustoleum primer doesnt stick to polyurethane. what should i do now?

quite often the new bumpers still have the release agent from the mold, no paint would stick to it, you should clean any new plastic parts with mineral spirits, or some solvent, acetone might eat it, but you really should clean it first. i played that game too once, but only once, good thing is that the paint comes off easy
