The show is similar to Myth Busters, but they try and 'invent' things. In tonight's episode, they're looking to do a bomb-proof building. They're experimenting with using Rhinoliner (the spray-on truck bed lining) to protect against blasts. Though this appears as a solid, they actually tested it by stretching it to 5 times it's normal length using 500lbs of force before it broke.
They blew up 2 trucks, one with and one without the lining. The one without the lining was blown to smithereens. The bed on the one with the liner stayed remarkably intact.
Next they took a sheet of plywood and coated the back of it with the Rhinoliner. They shot the plywood with a 12-guage using birdshot from about 15ft, and though there was a hole in the plywood, from the back (where the coating was applied), you couldn't even tell it was shot! I was pretty impressed!
Next they built a cinderblock wall and coated the outside with the liner. Then they set off a blast in front of the wall. The wall stayed standing (the test wall without the coating crumbled), though the cinderbloack behind the coating was totalled. However, another test wall with the coating on the back deflected the blast fairly well (they tested about 1" of 'flex' in the wall). Coating both sides showed similar results to the wall only coated on the back.
Regardless, I was pretty impressed, and was wondering if there could be a use for this stuff in bullet-proofing applications. I don't know how heavy the stuff is, but I'm thinking it would be great to spray on (and under) Humvees and other military vehicles as an added layer of protection against blasts, but how do you guys think this type of material would hold up against common small-arm calibers? (Is this a "What caliber for RhinoLining" thread?) I'm guessing a rifle bullet would have a much more focused impact than a blast or shotgun, but do you think it could hold up? I'm also thinking of a use at a range as a backstop, something like those little boxes with targets that catch BBs and pellets from air rifles, but on a larger scale (ie, a 10' high box deflecting bullets down into the ground).
Also, how much do you think it'll be to cover my Avalanche with this stuff? I do live near Newark, you know...
