If you buy vinylester/polyester 5 gallon pails, 10lb bags of aerosil (cabosil), and rolls of fiberglass. You can set up an account with composites One (
www.compositesone.com) . . . they also sell nidacore. I think they only sell epoxy resin and hardener in 55 gallon drums.
Otherwise:
www.uscomposites.com is pretty cheap (even with shipping).
This is the closest location to you.
