Contour Enthusiasts Group Archives Forums Modifications Aesthetics Brown/yellow spots

I washed the SVT and was disturbed by something I found on the rear of the car. There were about a dozen or so tiny brown spots on the bumper and the bottom of the trunklid (no where else on the car). They weren't coming off with soap and water, so I took the clay bar to them. That removed the brown "crust" but left yellow marks behind. No amount of claying would remove the marks. So, I started working with what I had, trying various things. I was able to get the marks out of the trunklid using a paint cleaner, but the marks in the bumper wouldn't even come out with rubbing compound.

I think they're small and light enough that only I will ever notice them, but it still bugs me. Is there anything else I can try?

sounds to me like tar from a newly paved road....it can be a PITA sometimes to get off. Reason I say this is b/c each time I have taken tar spots off it starts as a dark brown dot and as it comes off it gets lighter (dark brown, light brown, dark yellow, light yellow, and then eventually gone).

Do you recall driving on a newly resurfaced road recently?

As far as getting it off I've always had luck w/ the clay bar. Not sure what else would work well. Perhaps simple green

Yep, been there before...i once had a bunch of specks and strings of tar on the body behind each wheel...WD-40 and rubbing alcohol worked for me....whether its bad for the paint i don't know, but it worked. Rinse off with water after.
