i used some behr porch paint. about 30 bucks a gallon. get it at lowes, best price. they can mix any color and type of finish. i posted some picts of my boat in progress. first coat covered pretty well. sticks good. the guy i bought my boat from is a retired painter and thats what they used on tin boats.
good luck. post some picts so we can see how fugly it really is
