Partly due to the miles of muddy single track to get to my house I don't tend to be too precious about polishing every part of my M every weekend but with such nice quad pipes it's a shame to see them sooty inside. I've polished the inside edges by hand before and whilst therapeutic it does take a while. Last week I ordered a 60mm Dome cotton polishing mop that has a 10mm shank to fit my cordless drill, added some metal polish and gave it a go. 10 seconds in one direction, 10 seconds in reverse at a medium speed and the result is superb and just so easy, if you aren't already using this method I recommend it. Will post piccies up later.
