Liquid armor

This could be very useful. Lighter and tougher body armor. It will never take the place of defensive weapons but I would consider wearing body armor on a regular basis if it were cheap and comfortable enough. I carry my handgun whenever I can but in many cases you may end up taking the first hit before you are able to take the attack to the aggressor. And of course there are those times when I’m not allowed to bring my defensive tools with me and body armor might allow me additional time to bring my hands and/or feet into range and absorb the attack while I’m delivering my own.
