Ken Mosier has provided me with some tips on how to polish up the black plastic which I'll try in the next few weeks. ...
Did he have any suggestions on how to remove the argent paint from a grille so as not to damage the black plastic underneath it so you can leave it natural black??
Years ago 69Mannix suggested to me soaking the grille in old brake fluid to remove the argent delicately. I've never tried it.
