Yes, your right about bulletproofing... But like I said, the stuff I will be using is a 'rubbery steel'. It can absorb any impact, and retain its shape. When the subs are under construction, where we lay the sub on this skeleton like undercarriage, we use tiles made of this material to lay the boat on, and boy are they tight corners to wear you think they would rip, or pierce... But not a mark. This material is as hard as steel, but swing a hammer into it, better hope your wearing a helmet. The bullet proof was just a test... The idea was never to make a bulletproof MC suit, but just a stronger version, where your able enough to wear, and kneel on, and really bang into things, and can take severe abuse without taking much damage, but when these materials are layered in this fashion, made this very flexible hard shell. I was curious, and had my friend bring over his pistol, and AK. Fired 1 shot from each into it from a distance. The AK almost went through, and the 9mm impregnated the plate with the bullet. I called my friend again, I may have exaggerated the width of the plate... Its about 1/2" thick, not 1/4". Remember, I said this stuff is called an incompressable material. Its usually used around special areas on the sub to prevent from getting crushed at deep depths from the pressure. I also got corrected at work today... The psi of water blasting wasn't 5,000... I guess I missed a 0. Its 36,000 to 50,000 psi. The conversation came up cause me, and my partner had to clean up areas of the boat where they had done it, and fiberous chucks were everywhere. Anyways, this project is not 100% yet. Me, and my friend are still thinking if it will be worth it, or just build it the conventional way of clay, or fiberglass... We are just afraid it would take too long with the material we wanted to use. But aluminum, and epoxy is still staying. Its the primer kits which will be hard to sneek out of the security check points. They are awkward shaped, and only come in small kits. Probably take about 5 kits pure layer, and then per body part. Hell, we are still not sure if we should build a mold with plaster, and silicone, or pepakura... Not sure which would yield the best results, in realism, and quality. We want a very heavy weight suit, and very durable.
