mat/cloth + resin + hardner = fiberglass

sorry i was just a little confused. initially, he listed resin, but aneonrider said just add it straight to the MDF and i got a little confused.

you could also try some stuff called kitty hair, its resin and chop mat combined, stuff seals **** right up but its hard to sand so if you use it be sure to smooth it out nice before it dries
