Personally I use Dodo Lime Prime on my plastics and it will also work wonders on scratches... Sorted my mums car out when she reversed into the gate and when the GF pranged hers too - both my hand. You really couldn't tell there was any damage now its good stuff. Used Lime Prime on the door handles to remove the scratches that build up from people wearing rings and it also resotres the vinyls on the R27 if they get watermarks.
