For me I don't use any glue to hold in my inserts in carbons for tuning.I like to use the saran wrap method.I'll push in the insert with alittle saran wrap.It will hold the insert in tight enough for shooting and tuning.You will need a softer target like a bag target.So it doesn't grab the arrow too tight on removal.I'll shoot through a shallow box,the box holds the arrows position and the bag target doesn't grab tight enough to pull insert out.I get my tuning done quick and easy and didn't put any heat on my carbon shaft.Been doing it this way for a few years now,works great for me.
