I haven't had problems with stickers coming up, but I do a few things that supposedly help. First, I trim corners where possible so that the profile is as rounded as possible. Those corners are what usually seem to come up for me, and some trimming seems to help for some strange reason. I've also heard of putting a thread wrap over the entire sticker overnight to make sure it is stuck down good. My stickers are usually manufacturers stickers, so I put a wrap over each end that mimics my guide wraps. It usually looks nice, IMO. Heat may be easier, though. Finally, I put stickers and decals down on a light coat of cured finish, then finish over the top. I've also put CP on the edges to help with peeling in the past, and that might help keep the finish from getting to the adhesive.
Better to be an active environmentalist than and environmental activist.
