We always recommend medical adhesive (i.e pro-adhesive, pros-aide, etc) for most all our customers. It's water based and has no solvents or fumes like spirit gum. I has a better hold than spirit gum too. Yes, you will need an appropriate remover (i.e. Super solv) or you can use 99% isopropyl alcohol to reactivate the glue and remove the piece. This will still leave residue on the skin that needs the adhesive remover, but it leaves the prosthetic egdes intact. Make sure the remover has no oils in it or reapplication will be near impossible. Hope this helps! Larry Bones - Bone Yard Effects, Inc.
