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.
