First, are you using the original BMF?? I've had the same problem when I used the Gold BMF to mask, and then I read the sheet that comes with it, and it says to only use the Original BMF for masking. Second, if you are, you may want to pull it off a few hours after painting!! I usually paint in the evening, and then remove the masks when I come home from work, as I have had too many problems with leaving masks on for more than a few hours no matter what I use. Alcohol will remove the residue, but be careful not to get it on your frame, as it will start to remove your finish!!! Good luck!!! BTW, check out their site, and see if they have any more ideas: http://www.bare-metal.com/
