Auto body repair & detailing: paint scratched, side mirror, hand glaze

Question
My wife rubbed the whole side of her expedition against my side mirror of my truck when pulling in the driveway.  There is a thick black streak of plastic down the whole length of her car.  Tried a heat gun to get it off, didn't work.  Any suggestions?

Answer
Hi Chris! purchase a rubbing compound at you local parts store. Apply it by hand only back and forth. Then use a finishing compound in the same manor. Finish off with a hand glaze. You can apply this in a circullar motion. This should take care of your problem. Thanks!
