Simond's Fiberglass Woven Roving (18 Oz, Plain Weave) (50" x 36 ft. / 12 yd. Long) https://amzn.to/2Lp82kP $57.49


Why 18 oz cloth? That's some heavy stuff that is going to soak resin like a fat sponge.

Yes for compression strength, but nothing else.

Just driving at highway speeds, think of all the forces buffeting.

Without a good tensile / shear strong skin+adhesive, everything will fly apart.

Yes super thick glass is overkill, but. . .
