I'm going to make a start on my Boleros soon. I was thinking of respraying them but on closer inspection the spokes aren't too bad - it's just the rims which have lots of peeling lacquer. The insides and the lug holes are covered in black road ****. What's the best way to give them a good cleaning? Not sure what to do with the rims though as they were polished so obviously have no paint on them... I guess I would have to spray them?
