ok, i guess i forgot to tell you the whole fiberglass method. sorry. im gonna explain all the stuff you need to do it. so the stuff that makes it fiberglass is, well, fiberglass. it comes as either as a material type, or as the raw fibers. the material type makes for a smoother finish, and is easier to roll out.the raw fibers are for stuff your not gonna see much. heres the mesh:

and the stuff that holds it all together is polyurethane resin. probably available at your local hobby store, if they sell planes, trains and model cars, they might have it. if not, you can ask, they'll know. if not, you can try various online stores. heres one:

and to put it all together, you have to mix the resin to the directions, and apply it one layer at a time. only mix enough resin to do a layer at a time. and make the batch so it dries slowly. you dip the fiberglass in resin, and lay it on the buck( in this case, the foam tank), and smooth it out. you can use a rubber roller to properly get out all the bubbles, but i dont think you need it. you should let it harden for at least a day, and then add layer by layer. when it sounds nice and hard, your done, and all you have left is to prime it, sand and bondo to your hearts content. then paint like you normally would, and presto!
i know it sounds like a long process, but it would be a good experience and it would be fun(if you like making things). wear gloves, work in an open place(i think outside of your garage, or with a fan blowing outside your garage), oh and wear clothes you never wanna wear again, including your shoes. you might even need a face mask thing, like the doctors wear: the resin does smell, but i choose not to wear one cuz i dont like them.
heres somethig made with this method:

i dont know what that is, but i shows you what it looks like. hope it helps, and i hope you like it.
