Pepakura... Yes... But resin, no. Bondo, no... I work for a government defense yard, where we build submarines for the navy. A lot of the stuff we do there you need secret clearance, and government ID's. I make molds all day long, and use special materials in the skills we use there. But certain materials have special properties, which can't really be pocessed from the public, and which is for navy use only... But, I sometimes tend to bring my work home with me through the security checkpoints... Any ways, instead of using resin, we use this special primer/adhesive... Its incompressable, and just about the only things that can damage it are a sludge hammer with huge chisel spikes, or 5,000 psi of water blasting... Other then that, it sticks to anything, and is permanent... It has a very flexible, yet stiff property, and almost impossible to break, no matter the thickness. Its a amber color... It cures extremely quick, within 3 to 30 minutes... Depending on how much is in one spot. If left in the can, and not used, but mixed, the can would easily burn you from the heat generated. But when brushed on thin, takes longer to cure since there is less heat generated. It can be used in layers, and painted on when fresh, but it must be used in kits, so little at a time. The second material, is like bondo. Same concept as the other stuff about the curing. Less, takes longer to cure, and huge amount takes 2 hours. Plenty of work time, but when its done, its as hard as steel, and stiff as a mother f*****. Its a special metal epoxy adhesive, thats why. You can shape it, and mold it. Very thick stuff, and almost the consistency of soft clay, but very sticky. Can be applied to almost anything. Full cure is 16 hours. At that point, its hardness is great, and just flexable enough to hold its shape to whatever surface you apply it to. If it can be used to build submarines for the navy, then it can be used for a chief suit... Both materials have unbelievable properties. But both are also extremely toxic, with the primer kit containing pure isonate. Can you say, Tumorous? But when hardened, and painted, completely harmless... I was thinking of giving both chemicls a test run on a chest that I am going to begin to build soon. I just picked up 300 sheets of 110 pound cardstock, and about 100 pieces of 8x10 aluminum flashing and small zinc plated machine screws with hex heads to integrate into the layers of the armor on every flat surface or large area. I already tested some to see the strength... One layer cardstock, then primer, then aluminum, primer again, then metal epoxy, then primer yet again... Then paint. Results... 1/4" thick, and knife proof, and also 90% bullet proof. Yes, bullet proof. Depending on distance. 100 feet away, your good to go. Point blank range... The bullet still had trouble going through, but made it... But it wouldn't atleast go THROUGH your body. LOL I'll let you know how the tests go when I find the time.
