Hmmmm, I'd want to be totally sure of the fact that - that coating will last before applying it to any of my rims or other exterior car parts...
Alot of pressure pack stuff you get over the counter isn't as good as getting it done professionally when it comes to exterior/heavy duty wear and tear paint/coating jobs...
As for the result not a fan myself, the original machined finish on those Golf rims looked 10x nicer in the 1st place
