You can pick one up pretty much anywhere. The one i used was like this 3m. Pretty much it uses the friction from the rubber wheel and that heats up the glue. It work and it isnt a pain at all. All you do is go back and forth on the stripe until its gone, do a little section at a time. wipe with a terry rag and thats it. here is a like to a pic of one on 3ms site. its called a "stripe off wheel".
