I need advice on painting some scratches on the bottom-side part of my 2005 hyundai tucson. My tucson is a 2 color combined, the top part is blue and the bottom part is dark grey, almost black. Check the picture to see the part where I need to paint the scratches (this is not a picture of my tucson, I got it from Hyundai website).http://bancouno.0catch.com/tucson.jpg
The scratch is in the area rounded with red color. The material on that area is some kind of plastic I guess, not sure if it is the same material as the bumper, so I do not know if buying paint for bumper or paint pen. Also I do not know the paint code for this area and it is not specified in the label on the driver's door.

Oh I forgot to mention that the scratch actually looks like a peel, and it is white, I guess the original color of this area was white.

If you are spray painting a non-metal surface, such as a urethane bumper, you should order the Bulldog Adhesion Promoter as this is required for proper paint adhesion. The Adhesion Promoter is only required when you are spraying the paint and not for the touch up bottles and paint pens. Rubberized Primer is still recommended for unpainted non-metal surfaces and should be applied over the Bulldog Adhesion Promoter.
