Ok, I recently decided to shave my "Civic" and "DX" symbols off my car. I originally started by heating both with a hair dryer and then pulling them off with dental floss. My problem is this, There is still some excess residue and plastic left on my trunk. I've tried Goo-Gone, floss, and more hair dryer, but nothing is getting these last few peices. Anyone have an idea of what to try?
