I think I am epoxy sensitive. I get a red rash behind my knees when working with the stuff and wonderful cold-like symptoms when the uncured dust is in the air. I used MAS on my 2 S & G boats and really want to build again. Does anyone know of any significant chemical variation between the popular epoxy resins? If not, does anyone know of a viable alternative to epoxy resin? Finally, how uncomfortable is a Tyvek suit for working with epoxy?
