Here are some pics of the foam tank I carved to use as a positive mold to wrap kevlar around. I made a mold with plaster of paris of the underside of the stock tank and filled it with expanding foam. Then I glued a block of foam on top of the molded foam and freehand carved the shape of the tank to my liking.It took a few hours to make. i still need to finnish off the edges in a couple of places and smooth it out some more before its ready to cover. I spray painted it black to get a better idea how the finnished product will look. Now I just need to order some kevlar and resin and I'll have a tank. I'll post pics of the finnished product when done.
