So i decided to try the plasti-dip stuff and let me tell you it works awesomee. first i tried 3 coats on a plastic bucket and let it sit for a half hour and it peeled off with a bit of picking at it. and it was only two coats. so then after dinner last night i got to taping off my car and tried the rear valance. came out awesome. I did like 7-8 extremly thin coats and it looks great. only thing is that since its a little rubbery the paint sticks to the car and the tape so i got some rough edges in some places, so i need to find a way to get rid of that. but other than that it worked and looks great. heres some pics.
