You are behind the times McDave! Big Jim's Quick Stick hot melt is the only glue I use for inserts on my carbon arrows. I have tried just about all the other glues, and nothing beats the Big Jim hot melt, esp when you are using expensive brass inserts that need to be recycled when the arrow is damaged. I have been using that glue for 3yrs now, and have not lost a single insert, and removal is a cinch with never ruining a shaft!
To the OP, yes, you heat the insert, dab it in the glue, and then insert it into the shaft.
If you are using a hot melt like FerruleTite or craft store hot melt, it is likely that it will not bond well, and you will lose inserts in targets.
