After having the new head light fitted and the other one looking a bit shabby I finished polishing the L/H headlight and used toothpaste to get it back to new looking again. Standing back and looking at both I can't see much if any difference between them so just to let you know, plain label toothpaste did the job with a little elbow grease and a kitchen non scratchy scourer. I couldn't find the disk for the drill as it is in hiding somewhere.  I put a coating of 'Rain X' on both while doing the windscreen to help repel water. 

Tug now all done and dusted and ready to get back out there.
