I just purchased a new front bumper rub strip for my 87 GN. The one I am recieving has the white painted stripe applied. What procedure is the best to remove the white painted stripe? Ive read to use a solvent. Which one will not damage the rubber. Ive also read to use a compressed air gun. I know these rub strips are available without the white, actually Ive heard that they all come with the white, it's said the white is "professionally removed". How are they doing this? I want it to look perfect, like it was never there. Any detailed help would be appreciated. Thanks Dave
