I’ve been polishing it up with Brasso and also tried the Dremel and the polishing block which came with it which I assume is jewellers rouge, using the Dremel I’ve been wary of localised heat, I think there is some progress but it’s going to take time. The scratch is actually slightly above my eyeline but you never know with a MOT fortunately I’ve got until April.

Mike, thanks for link to Frost kit I think it’ll be worthwhile getting one and giving that a go.
