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?
