Thanks. it looks good. I just finished a Don Hill 17' Db and I Am a few days from painting it. I was looking at the Garage floor epoxy paint at lowes for the int. and the Interlux at $100 per gallon for the ext. I will look into the Duramax now. I put 20 oz Biax fiberglass on the bottom and a 4" 25 oz strip on the chine so in effect I have a fiberglass pan on the bottom of a framed boat. I have coat it for the bottom.
