Just finished laying up the deck with 1.5 oz chopped mat in poly resin. I had planned on top coating that with 18 oz woven roving, for strength and longevity, but the resin usage is really startin to take a financial toll. The roving is bought and paid for, months and months ago, but I'm starting to question whether it's really necessary or not. Some knowledgable feedback is needed here. Thanks in advance. Kevin
