I use hot glue as well, high temp glue gun. I never had a problem but once I was putting together a clip and noticed it wasn't sticking as well. Come to find out the heating element in my glue gun was going bad (guess I use it ALOT
) so I had to go out and buy another one. Sad thing is the other ones have not lasted nearly as long or as nice as my surebonder one (which I couldn't find another one like it). Guess I tend to over use and abuse. lol.
