There are those who don't ever loose inserts and they use "***" kind of glue. Why are they successful and others aren't? I can't say.
What I can say is not all hot melt is created equal. Yes, there are other types that will probably work just as well, but I can't say until it is tried and proven to be good or bad...by then you will be plenty frustrated.
We have been very successful with the quick stick that we choose to use several thousand times a year. Just don't use any more heat than necessary and never apply heat to the shaft.
Last year we sold over 4000 dz GT's and if you requested us to install inserts, we used our quick stick...No, we didn't clean the shaft. If there was an issue, we were never informed of one...not that came back to me at least.
When we used the Gold Tip tip grip, we would get dozens of calls a year and back then we did clean shafts before installing inserts.
Thanks ya'll, BigJim
