Thanks for the suggestions. The paint pens aren't expensive, so they seem like an economical way to go.
I have another question for you regarding my car's paint job since my last post/your answer...
While washing my car yesterday, I noticed what looked like an oily residue that had dripped on the roof of my car, and dribbled down the side onto the rear. This did not wash off. I park in a garage, on the bottom floor, and a co-worker had the same stuff dripped onto his car as well. Any idea what this can be, and how to get it off?
Thanks in advance for any insight you can offer.
