Go to a motorcycle shop and buy some Novus Plastic polish(they use it to polish plastic wind screens). Use a very soft non abrasive cloth and buff the hell out of it. You will be suprised. Get the Novus No.2 it is a finer polish than the No.1 which more of a rea; scratch remover it is better to start with the fine stuff and polish more.
Removing fine scratches on tt dustcover
Does anyone know of a way to remove the super fine scratches, that accumulate over the years, on your tt dustcover? Can you make it look like glass, or is that a little too picky?
