For structural layups I use E-Zpoxy. It seems to me that I've heard of other structural epoxies, but the E-Zpoxy is what Rutan recommended after the original stuff became unavailable.
For filling and sanding I use West System with their Microlight (410) filler.

What type epoxy is everyone using these days is it E-Zpoxy or some other brand. Does anyone have any of the old safe-t-poxy hardener (Part D hardener) that is still good and unopened. I know there is a health risk with it and some say it's not good but there are a lot of aircraft built with this old epoxy. Please reply (epadams@... <mailto:epadams%40frontier.com> ).
