My truck has some 3M double sided type above the windows were it used to hold onto some of those wind deflectors, however I decided to take them off. On the passenger side the tape was quite old and I was able to remove it with only moderate difficulty using a plastic razor blade. However, the driver's side tape is fairly new and still very tacky. I've tried both plastic and steel(very scary to use on paint) razor blades and they both just seem to remove the top portion of the tape, leaving a very thick and sticky residue that refuses to come off.
Anyone have any suggestions?
