No it won't. It doesn't melt in the sun, you're actual able to post cure it at 150 degrees. Occasionally I will use a heat gun set on high and bucket of water to bend a thin piece but its not easy, and the thick ones are almost impossible. Yes it is a 1:1 ratio. As for durability it depends on how thick you slush it. For instance I can stand on my chest piece, which would break vaccuform ABS or fiberglass but I wouldn't "bounce" on it. It's very easy to paint, I've seen car body kits made out of it. Many many times stormtroopers would come up asking what my suit was made out of, and I'd tell them to punch me in the chest as hard as they can, a situation that would happen once an hour or so while I was wearing it at a convention, they always did it and always regretted it, they never left a mark on it. I've even played paintball in mine. Also a lot of things depend on the actual shape of the piece we've thrown some pieces across our shop and had no damage, while other shapes you wouldn't want to drop off more than a ladder or so. To work with a cured piece you'll want to use power tools, a rotary sander, a dremel, and a drill. I would also recommend smooth-ons mold material we use their http://www.smooth-on.com/PDF/Rebound%2025%20-%20TB.pdf Rebound 25 it's a platinum cure mold and has good a nice rigidity to keep shape, in addition to the mothermold.depends on how thick you make it...but i wouldnt keep it in the sun it well melt

Technically any sort of containment field would work, I've used clay, cardboard, foil, light plastic, my own hands etc.. One thing that might make it easier would be to clearcoat paint your plaster mold first giving you a slicker surface (there would be slight detail loss there), and also use a releasing agent. Also mold/piece shape is a factor since the resin and mold would be rigid, you would need to avoid locking the piece into the mold if you wish to reuse the plaster mold.Omega said:Would plaster molds work with this resin?
