Quick question. I put that stuff in my Challenger too. Think the stuff I used was called BrownBread. Its just like the Fatmat; asphalt based, adhesive backed, foil topped. Question is, how do you REMOVE the stuff if doing a rotissere resto. Has anyone done that yet. HOPE it's not stuck down as well as it seemed when installing. I plan on stripping my turn and having the bodywork and paint redone.
