i love plasti dip. but be sure to make a lot of coats. if you don't, it gets harder to peel especially if left on for a very long time. i ran into that issue with 2 out of my 4 rims because i was running low. i litterally had to powerwash and use a
rag with a buffing compound and rub for hours. anyway looks good!
I had th same problem when I dipped the chrome on my rear bumper. In certain places the chrome trim abuts the bumper. If you're careful, you can mask right up to the bumper in the places that are problematic, and then peel it off as soon as you're finished spraying the last coat. I did that and it seems to work. It's just annoying and you just have to be careful to not let the tape get into the wet dip.
