well i tried the epoxy casting resin from micheals. it sucks.
i cast a 4 ounce skull. while it doesnt set with a tacky surface, it does come out a light amber, instead of water clear like the urethanes. also it degasses as it sets up, which means the chemical reaction that occurs while it sets causes micro bubbles in the resin, giving the whole thing a cloudy appearance. (if i had put it in a pressure pot while it was setting, that wouldnt have been an issue, but most hobbyists dont have a pressure pot at home. (the cure time is 24 to 48 hours depending on the thickness of the casting.)
the upshot is that it has all of the disadvantages of the urethane clear resins without any of the advantages. the ONLY thing it has going for it is the non-tacky surface (as opposed to the polyester clear resins also available at craft stores). all in all youre better off contacting someone that distributes bjb or smooth-on products and go with one of their clears.
