Never done it before but I read an article on it that I cant find, so same as any rawing, go light on the paint stripper and put towards the middle to not damage the urethane. The paint stripper will have the edges peel up outside the area it was put anyways. Hope it works!
don't use paint stripper. Wheels are Eloxated not Painted.
Oven cleaner works like a charm. But it might attack your PU a little. But i rawed some Anaquauauauaauauuda wheels and they still worked fine so yeah.
Just do it like that. But check like every 5 mins if the urethane reacts funny.
