It is somthing called Boat yard I think it's made by evercoat. All I know is what the guy at my local marine supply store told me. He said that it is a polyester resin that is on sale from $20 per gallon to 12$a gallon Thats all the info I know so far but if this stuff is ok I don't think I want to pass it up.
