Starting to dig into my Hero Falcon now, and have used one of those cheapie silicone mold kits from Michaels to cast up one of the engine vents off the BMF. I've now got what looks like a decent mold, and am itching to start making replacement vents. Thing is, I don't have access to a store to buy casting resin, so I'm trying to work out an alternative. Anyone know if 1) I can use the resin that comes with fiberglass kits to pour these? If not, any other household suggestions that won't destroy the silicone? Also, since this info isn't in the limited instructions, 2) on a silicone mold, do I need some kind of mold release agent and 3) since I need to make at least 7 of these (6 vents, and the two smaller vents on the top of each docking arm), what's the best way to keep the mold in reasonable shape as long as possible? Thanks!!!
