thanks Doc, it took me a while to catch up with this topic.
i've just cleaned up the cases and fork legs on my old RT1 for no other reason than the motor just seemed to lend itself to the idea of polishing and i've never done it before, so now seemed like as good a time as any to try it.
i just used my 6" pedestal grinder fitted with different polishing wheels from bunnings. i'm still yet to do the silvo but should get onto it soon.
thanks for the help fella's!
