oooh, fiberglass is so fun to work with!!!!
if u like itchy skin and u don't mind yelling at the gooey mess in order to make it stop sticking to your gloves.
you can just buy some resin (which usually comes with hardener) and some cloth.
the resin you can find at a hardware/big box home improvement store
u can use the one with the picture of the corvette on it.
the cloth should be the kind that is woven together in a mesh, not the thicker, loose one.
or you could go to a surf shop (which are on every block where i live) and get a fiberglass repair kit for like ten bucks....it will come with everything u need.
it's all the same stuff......get resin.....get hardener.....get cloth......and enjoy.
