Paint or powder?
Yes, my current GP's are chrome. Its a finish I hadn't even considered before having those, but I love it.
You think the chrome will work on non banded?
It would be a place local to me doing it, they mentioned chrome when I enquired earlier in the week. They said it requires a clear top coat though to prevent it dulling over time, I assume this is common practice? A quick Google suggests so....
Im not sure about the clear top coat as Jamie did mine. However I did ceramic coat them before using them.
I dont see any reason it wouldn't work non banded.
