Can you describe this heating? Perhaps you are seeing the whiteness around the glue, which is harmless.
There is no heating involved either via chemical reaction or otherwise with the Fastset or any other glue for fletching.
Personally, I find FastSet gel to be one of the strongest bonds I've ever come across on both carbons and aluminums. The Plastifletch Elite vanes are great, and the AAE Fastset gel is recommended for them.
That's what I've been using for years, and I'll give you my arrow if you can pull one of the vanes off with your bare hands!
I totally agree with BowhunterNJ, this combination of vanes and glue is the best bonding to a carbon arrow I have found!!! I have never shot aluminums so I can't speak for them. I have also used Fastset gel with other brands of vanes as well with the same results.
As BowhunterNJ said, if you can get a vane off my arrow without using a knife or razor blade it's yours.
Deerhaven, make sure you clean your shaft with 90% alcohol before you fletch. Fastset gel is pressure activated which only takes a couple of seconds of pressure and you are not getting it off after that!!
I've been using Elite vanes and AAE glue, then gel, for about 10 years now. I'm with the others, if you can pull one of my vanes loose with your hands I'll gladly give up my Gold Tip to you. They just don't turn loose. I use the gel now and only leave my vanes in the clamp for about 10 seconds. Haven't had one come loose ever when stuck to carbon or aluminum with that combo.
I also have excellent results with the Arizona Fletching Tool w/AAE vanes and their fast set glue. They put a chemical on their vanes to react with the glue, so if you're taking a solvent to the vanes before you try to glue them up, that could be a problem.
