I have a 94 which I took the G20 off of. What you read here is right. It is double sided tape, and you do want to heat it up. I used Goo Gone and it took away some paint (I was rubbing white off too but nothing noticable) so I switched to 71% Rubbing Alchohol.
My car is a 94 and I live in the desert and their was barly any fade were the letters were/are (Unless you look REAL close) after I removed them.
Go get our trunk (car) washed/waxed/buffed and it should be good to go.
