Forget old fashioned calvarium clamps and frustrating muscle ties. Tech-Bond Cranial Gel Super Adhesive is the best way ever to re-attach the calvarium on a posted body. Simply apply a bead of the Cranial GEL along the cranium (or use a number of drops along the same area). Spray the Activator on the cap, place the cap on the cranium and align. The cap will set and not move.
