The decals should not come off that easily. I have a Nude Fly. It could be that whoever applied them picked up the wrong ones. They look the same except the nude version are I believe green on the back.
Acetone takes them right off. I got mine in the hardware store. There really isn't much to know except to wear gloves.
I'd call Craig and get his feedback anyhow. I never had a problem with any but the top tube. I applied a new one from a fresh batch of decals and that is holding up fine.
