Ha ha went to the marine supply place today. Would have cost me over $300.00 to go with their epoxy. I told the guy I was building a fish tank not a speed boat. A little disapointed I just decided to fall back to about plan "C" and use polyester fibreglass. I'll get some kind of epoxy sealer later. My dad had a huge roll of matting and about a quart and a half of resin I talked him into donating so I did some prep work and laid the first sheet of fibreglass. Looks not too bad considering I've never used cloth before. I didn't mix quite enough resin so there was a panic moment there near the end but I had used less hardener to give me a little more time to mess around with it so things seemed to have work out ok.
There's not much a selection locally for epoxy based paint. A couple of places sell this Rustoleum epoxy shield, has anybody used that, if so how well did it work. I can buy it for less than a hundred dollars a gallon so it's high on my short list of options.
