I was watching TV earlier this morning, and I saw this new substance called "Zubber". I immediately thought it was some sort of play-dough, but upon further inspection, it is actually a sort of epoxy putty for rubber. It comes in a package as a moldable substance, but upon hardening, it has the consistency of rubber. This has endless applications for Nerf modifications, and even homemades. Here is the site, The Amazing Zubber.
Some possible applications could include custom molded plunger heads, permanent sealant, and even rubbery grips for guns.
