Loctite Super glue gel in the blue tube.
I use to only use hot melt but never once turned an insert after it's initial installation so after losing a couple broadheads in their target I went with lock tite
I don't say this to be contentious, but the last thing I want to use is an insert adhesive that will never come out.
I'm the opposite........I NEVER want those suckers to come out once I put them in. I've had way too many hotmelted inserts come out of my arrows for my liking......and usually inside a target.
For HIT's I use the 24 hour epoxy, for regular inserts I use Gorilla Super Glue. I've never had a HIT come out, even hitting something extremely hard........but I have had some Super Glue ones pop loose on hard hits.
