Used gorilla glue on 3 arrows where field points needed replacement the other night and let set till morning as I wasn't sure how much time needed to set unlike hot melt I just let cool down or run under cold water and good to go
1- Note to self with gorilla glue. "Use slightly less" Yes it did expand slightly out of field point and had to be cleaned up like Mark said. But no big deal.
2- Yes holds like concrete.
Nice to have a couple options though hot melt is best for broadheads so they can be tuned if needed.
