Personally, just powder coat, diamond cut can be a pain ,you only need a tiny chip in the coat and water gets underneath the lacquer and looks awful .Would you do just powder coat or also do the diamond cut?
Powder coat if you can stretch the budget, but the way I see it... Painted rims will last just as long
View attachment 49267 My Wheels are Split Rims, I believe 3 way splits, most places I’ve asked, won’t touch them unless I sell the car to pay for them. The outer rims are diamond cut, but the lacquer is coming off, I’m going to try to remove the lacquer and repolish them myself without splitting them...the photo shows a wheel before the lacquer started pealing...
