Ok, I'm an A&P Mechanic and RV builder. I've done a little composite work throughout the course of my job and for the RV, almost exclusively using West System.

It has come to my attention that this may not be the BEST epoxy to use fore structural fiberglass work, so I was wondering what is? I have a Rutan 'practice' kit with a little EZpoxy, and I was going to try my hand at using that. I know Vinyl ester is superior for higher temps, but am hesitant because of the fumes.

For epoxies, is it there a better solutions than West for strength/weight? I've only got a gallon of it right now, so it wouldn't cost me that much to change except for the learning curve. I've used West both proportioned by weight (at school) and by Volume (with the pumps, at my hanger).

The applications vary from fairings and cowling repair, to complete aircraft structures (basically, I want to get very familer with one system that I can use all the time).
