Drew is someone I admire a lot, but will disagree on the hotmelt.
I worked PT for 2 yrs for a large wholesale archery distributor in their smaller retail store locally.
All they use is the brown hot melt sticks. They have a "melt pot" that they plug in each AM and we use that all day, adding sticks as we deplete the pot.
Their backstop is masonite on edge with big all thread cranked down. I've nearly threw my back out pulling arrows out of that miserable backstop...and we'd sell arrows, cut them, never clean them and just hot melt alum and brass inserts and take them out to the customer who'd pay for them, turn around in 10 min and shoot them. Only had one insert pull out I knew of in 2 yrs working there PT.
Go figure. I use it at home, but do use a q-tip w/ alcohol to swipe out the inside of GT's. That's it.
White/clear glue gun glue won't cut it though I fear.
I get my sticks from Braveheart...but there are more than one brand I've used successfully.
