downpipe cleaning question

[bludclot]

wet'n'dry (start with say 600, maybe to to 400 for stuborn areas) with plenty of water then rubbing compound then finally polish. mine came up gleaming like brand spanking! and it didn't take long.

i wire wooled my collector box and sprayed it using simoniz engine aluminium silver. it has lasted and still looks good today. i was doubtful when it was first done (thought it looked a little odd) but on the bike it looks the nuts!
