I have replaced my deck in my 66 glassmaster and i am getting ready to tabb the deck to the hull. I am using 4 inch 8.7oz e-glass cloth from us composites. My question is how many layers of cloth should I use on this to make it strong enough? I Know I will need to stagger the cloth on each layer since I only have 4in tape. Also I am using epoxy resin. I have already tabbed the deck sections together and I used 4 layers. Thanks for any help.
