I did mine myself using nitro-mors, had to do them a couple of times to get all the paint off but the end result looked good. I just taped up the paint which i didnt want to remove then brushed the nitro-mors onto the outer rim left it a few minutes then hosed it off, then repeated the process, there was no need to polish them up with wet and dry afterwards either, just a good buffing with some autosol!
