[BOBZBUBZ]

I’ll second the performance of Autoglym trim restorer. I’m a detailer and use it a lot. My bubz trims were nearly white now black and have been for 6 months now.

Used Blue-Tac and Autoglyn Trim restorer to good effect on the black roof trim today. The surface finish is still matt , I guess its just weathered, but the process has certainly got rid of the white polish marks and darkened it up a good deal.
