My wheels in this video are plasti dip..
And yep they do scratch but still haven't actually scratched through to the wheel just have light marks on the plasti dip, probably similar to what you would have on a wheel but this way you can just spray another coat.

My last car a Freelander 2 has plasti dip wheels and I see it driving around some times and it still looks good after two years which surprises me because I know they wouldn't have done anything to it or topped it up
