when you are using the heat gun don't let the covering get to hot. I normally set my heat on the low setting. Just warm it up in front of where you are pulling the covering off. I then will use acetone to get rid of some the small pieces that wants to stick. Just take your time.
What Gene is saying here. I use high heat myself but I have done it a bunch. Yes, depending on the color you are going to use the pigment of a dark color will show through most the time. Acetone and sand paper will cure that.
