When you use epoxy, it is a much better waterproofer ounce for ounce versus polyester so you do not need the mat. Straight 17 oz. biax will be sufficient but personally I am using 2 layers. I like overkill when it comes to my boat. The wood is your structure. The cloth seals the wood. I only go with 2 layers for the purpose of added protection against rubbing over time.
I like US Composites for epoxy and boat builder central for mat.

thanks for the info. I was going to use epoxy usa for the resin. Have you heard any negatives about their product?
Also I am looking at the mat. 17 oz 45/45 or 0/90 I see that one mas the chopped strand attached to it is the 45/45.
