That really didn't make any sense.
Only use elecrtical tape, because resin will melt the others and your pep piece will fall at the wrong time. Electrical tape is strong, and resin doesn't eat through it. The electrical tape will keep the helmets shape ( ha ha that rhymed). But i think to be on the safe side, just use glue. Elmers school glue would work ( but not glue sticks), only for a 1 buck 50.
