I second pros-aide.
I was initially pretty terrified of doing so because the reason I have it is for mixing latex body paint, but I didn't have any spirit gum handy and I needed to stick on my Robin mask, so I figured, whatever, no pain, no game, so I used it.
I didn't use the remover to take it off, because I've found that it just doesn't work for me, but even just peeling it off slowly was almost painless and didn't take my skin with it like spirit gum would even with remover. (And as Placebo said, it doesn't get crusty!)
