polyester resin needs catalyst to harden the kind used for boats/surfboards the catalyst is a form of peroxide,not the kind for cleaning cuts.
and of course epoxy is a 1to1 mix of resin and hardener.

so far my favorite glassing method is to use waterbased polyurathane, Varathane Diamond finish, after a couple of coats of DEFT brushing laquer to seal the wood.
I just use a high quality nylon brush to spread the poly from the center outward its fast dry,for quick recoat and hard as nails when cured it also is low odor.

almost all my painting is done with water based products. I have been using www.warbirdcolors paints with good results I am quite happy with the finish they give and being water clean up,there is no toxic solvents to have around.
there also nearly odorless which the wife and kids appreciate.
