Hey, I got a question. I bought my 91 bird about 4 or 5 days ago, it has benn sitting for about 2 and a half yrs, and it has some kind of stain on it, black looking....I already got the mildew and green stuff off of it, but it still has some black stains here and there especially around the gfx on the doors and the rear bumper. Got the rest of the car looking good. any suggestions would be highly appreciated.............THANKS!!

 

i like to use laundry detergent and elbow grease, usually gets everything off
