well as i said, it was already polished when i got it, but was really dull and grubby, so i stropped it completely, ie removed the motors, sensors, buttefly assembly etc, then repolished.
The main assembly where the throttle cable attaches to was not polished at all so that was a new bit i did.
The equipment ie the polishing mops and compounds i got from Colsoop, along with some good advice, tis a 3 stage drama.
Still havent managed to get in the very tight nook and crannies but im working on this. certainly its something Colin has got spot on and understandably is tight lipped on this (so would i if it was a source of income to be fair), but he has helped me thus far.
