I'm thinking about putting a bunch of stickers onto my commuter bike as a sort of anti-theft measure, and also to kind of give it that indie touch. I'm just wondering if there's anything I should avoid - how hard is it to peel stickers off the frame, for example? I hate it when you're left with that white sticky residue when you try and peel off a stubborn sticker and only get about half of it. But I'm curious as to what you guys do.
