AST resin?

Been reading some info on the AST resin system out of San Diego. It sounded like a nice thing, but I was told that it is extremely toxic to work with. Any one have experience with this and would like to share their thoughts?

I haven’t personally tried it, but there is a lot of discussion in the archive. Sounds like the only drawback, besides the cost, is that you have to build an oven to cure it.
