[quote=old man]Just looking to C-M-A and not have to back up for a redo.. and in what I'm reading, as odd as it may seem, a rough sand is required if you want it to stick. Just a note for those that have already purchased these, with the lip being "pulled" around the peak on our noses.. I would advise painting on the car. Painting it "flat" and then flexing it around is most likely going to crack any finish applied. Ran across this on a Honda forum.. this was brought in for rear damage repair and he had them install his spoiler. It didn't quite fit so this was there "fix".. He wasn't real happy..
