Where can you get silicone gel that can be easily molded that does not degrade over time?
I need some kind of gel padding for an underlayment on a suit of non-ballistics body armor I am building. What I want is some kind of mixture I can mix up, dump in a shallow mold, let it cure, then pull it out and cut it to shape and put it in the suit. Preferably this gel would be pretty good at absorbing shock and would not degrade over time if kept in a sealed environment away from sunlight, like sealed in a plate in the suit.
Anyone know of anything like that that is easily available and not over priced? I noticed the silicone used to make molds for casting, would that work? My friend suggested ballistics gel but it seems like it would degrade over time.
Any suggestions would be greatly appreciated.
