sorry for not being active for quite a while, but in any case, i just fiberglassed the right shin, crotchplate and the belt. for those wondering how much resin it takes...
Buy yourself the Bondo Repair Kit. The resin provided is enough to finish the belt and the crotch. The hardener is enough to harden the three together. What does this mean? It means, the resin provided in the kit is needed for two peices. With that being said, the plate itself may need up to three bottles. the ratio would be around 2:1, resin to hardener. As for the fiberglass itself, it took an entire sheet in the kit, and another half a sheet bought seperately to cover the three parts mentioned. In my calculation, it may take up to 6-8 kits, to finish the suit itself excluding small pieces like the knife, wrists, and handplates. and it took no less than 25 minutes to harden enough to smack against a wall without being broken on a sunny day. good luck to those who attempt it, as for me...im behind on GTA 4, SC4 and my suit. Tootles!
PS: I will post pics as soon as i get my hands on my missing digicam.
