I do it all the time... I have my molds for my halo armor that I cast in latex. I make sure I use a hotbox for curing. All I do is fill the silicone mold with the latex (usually handplate molds), put them in the hotbox (large plastic tote, with high temp heatpad in it) and let it stand for 12 hours. Be sure to keep it well sealed, so the moisture doesn't fully escape, if it does, the latex will crack.
