I own a G6 Coupe and while parked at school today I got 2 dings in my driver side door in the bodylines, they are small, but noticable because the car is black. I've looked around online and the only solution I have found is to use a hairdryer and an air duster, and there are conflicting opinions on whether this actually works. Has anyone tried this method or have another solution for fixing this (outside of taking it to a body shop or dealership for repair)?
