Does anyone out there know where to get materials in the denver area? Not much around here in the phone book. I need glass mat and resin and floatation foam, I found the marine plywood, 73.99 a sheet ouch, but worth it. Lowes had some cloth at 20.00 a sq. yrd. and 35.00 for a gal of resin. Seems a little high in price. any help would be much appreciated.
