Sawtex, Gorilla glue and superglue are 2 totally different glues. Super glues are of a Cyanoactylate base. Gorilla glue is a polyurethane base. They cure similarly (AKA water) but are chemicaly different.
Gorilla glue is a very powerful glue if used properly. Water is needed to kick it off. So dampen both surfaces before applying you're tip. A tip clamp is a must. When a polyurethane glue kicks off it will foam. It can lift the tip from the ferrule if not firmly held down. You need to protect the ferrule as the foam is next to impossible to remove completely from any surface it contacts, even hands. Gloves should be worn when using it. Unless you like brown stains on your hands for several weeks(go ahead and ask me how I know that). So it can stain almost anything. It is very good at sticking most anything to anything. But it must be used properly. Cure time is overnight to 24 hours depending on materials joined.
Cyanoacryates or CA use water or certain other chemicals to kick it off. The thicker the CA the longer work time you have. It does not form a chemical bond. It instead forms a mechanical bond. It wicks into small imperfections and cracks in the surfaces to be joined. It works best on porous surfaces, wood especially. The thinner the glue the less working time. All CA's are in fact fairly brittle. But if the glue is not exposed to shear and heavy shock loads it is fine. Working time is a few seconds to about 2 minuits. Set time is about an hour and 24 hours to full strength. Thinner glues you should protect the shaft and ferrule with tape.
CA if thin enough will indeed wick into the tip and possibly harden it. GG will not. If used correctly either glue will work just fine. CA and GG will not like an oily plastic ferrule like you find on cheap cues.
I also fly radio control airplanes. Have been for over 25 years. I have used about every kind of glue out there at one time or another. I build from kits or scratch. So I have learned quite a bit about glues. I even researched each type of glue to get the best results from them.
One final note of caution. CA's are a severe respritory irratant. use them only in a very well ventilated area. Continual use of them with out proper ventilation can lead to severe allergic reactions to them. So please use with caution.
I hope this helps some.
