So... About 10-15 years ago when I was little, I firmly placed a few thousand stickers all over the door... rather... anything with an adhesive backing, be it a stamp, a "I Voted!" sticker, to dino's, are now still on my door. Is there anyway to remove these? The adhesive is now firmly dry and picking isn't working out so well. Shall I just give up, sand it down, and repaint it at this point?
