I'd like to make some old style bonzer side fins circa. 1977.9 inch base x 2" deep. They were about 1/16 " thick, unfoiled and made out of fiberglass. I know I could make the material but I only need a small amount, less than a square foot. So, I'd like to know if there is a place in san diego where I could buy a small amount of sheet fiberglass.
