Thanks for the info guys, I will use water based polyurithane to glass my foam/balsa sheeted floats. I bought a can of it and it is made by the Varithane company I hope it works. Now about the spray pant, would it be ok if I used a regular interior/exterior spray paint on my floats and then put on a coat of polyurethane on top? Or should I spend the money and get a fuel proof paint? Is spray painting really the way to go or is there a different painting method?
Thanks again,
