Try sealing the surface with some color shifting spackle or Bondo? They're both available at True Value, Home Depot or Jerrys... Anywhere that sells power tools, really.
@ Nikkiolie: Then you should be fine. Hit up a Spirit Superstore or a Party City or something and grab a little bottle of Spirit Gum... It's only like three bucks and it never goes bad. People say to get the remover, but it's really oily and stinks to high hell, I don't bother with it. I just pull the prosthetic/wig hairline/stick-on piercing off and then scratch the residue off with my fingernails in the shower.
