You are correct. There isn't much difference between room temperature cured epoxy resins. The curing agents make a lot of difference in viscosity and pot life. The differences start to show up when you get into autoclaves and heated cures. There is difference between epoxy adhesives...mainly due to what the filler is...and there have been a lot of unsuccessful attempts to find a filler as good as asbestos. Basically, find a resin system you are comfortable using and stick with it. I am currently using a system from u.s. composites that I really like...it's their name brand but it is probably made by the same company that makes aeropoxy and/or west system.
