Depending on the color or your car, I have sucessfully used Langka (the blob remover) to touch up my cars and make the dings almost disappear. For solid colors it works well, for metallics nothing works real well. To use the Langka method you use your touch up paint on the ding and when almost dry you rub Langka over it to smooth out the touch up paint blob. On a white car I actually had dings all but disappear. It it sure a better way of doing it than touching up and trying to sand the blob away. The problem with some metallic colors is that you can't get the paint to match, so removing the blob is the least of your worries. I tried touch up paint and Langka on my artic silver car and it didn't work worth a darn. That is why I installed the clear bra.
