Don't waste a quality epoxy resin on fiberglass mat!!. It drinks resin like a sponge and has very little strength. It will add stiffness, but not streength. The worse the crack, the more you need some kevlar in there and then use a high quality fiberglass cloth, like military S-glass(the stuff you buy in the $9 poly bags at the FLAPS is E glass. Go to www.sweetcomposites.com for an excellent tutorial on resins and cloth and also god prices on all that stuff. Kevlar alone won't do it as it needs the stiffness of either glass or carbon to be the perfect repair.
