You might want to look at other options than using epoxy and glass. Take a
look at some of the synthetics such as Dynel,Olifin, xenole, Vectra or even
combinations of the above with glass.
Compared to glass the wetout using the synthetics is amazing. they're a joy
to work with.
you can look at than at WWW.defender.com
I buy there and have had super results.
These may or may not be the best approach for your project buy it might be
worth a look.
