Doug, Thanks for your answer. Actually, the 2008 Grand Prix has a plastic rear bumper cover and the lower center portion is colored flat black. My mistake was in getting Nu Finish on that center portion. I wonder if Acrilikleen or Prepsol would damage the plastic of the bumper cover?by pfarler - Auto Detailing: Secrets of the Experts
I polished the flat black area on the bottom of my rear bumper of my 2008 Grand Prix with Nu Finish. Now that it has hazed over, I can't get it off. What can I use to get this stuff off?by pfarler - Auto Detailing: Secrets of the Experts
