Well I have been testing and I didn't come up with much. I had two pieces of 1/2" oak that has had tape on it for maybe two months. They were scrap. I heated one piece up and didn't do anything to the other. The one that I put the heat to came off easier than the one with no heat. There was no adhesive left on either piece. I also put tape on 1/4" walnut, pine, and ply and got the same results. The heat does help with getting the tape off but I still believe you might break off small pieces. I should also say I am using the blue painters tape with "Edge Lock". I think the product number is "2093EL".
