Thanks Dan, that's the second thumbs up on Top Side Marine paint. I really like how your seat is configured with the 360 degree swivel option.I bought this boat used this Winter. It's a dozen years old. The original owner put epoxy with traction additive on the floor. The bottom exterior only is glassed for protection without paint. I went ahead and painted the bottom also. The exterior sides were original epoxy paint. I went over the entire boat twice with an orbital sander using 80 grit paper. Some areas sanded pretty well but other spots, like the floor, were bulletproof. At least I got the loose material off. I dusted it with a towel and then scrubed it with alcohol to remove the fine dust. 2 layers of Rustoleum Rusty Metal Primer. I read about it on some boating blogs. It's thick and tenacious and comes well respected even on wood. One quart did the entire boat.. The paint is Rustoleum Top Side Marine paint. 2 layers. It took 1-1/2 quart. Top Side paint is fine on the bottom also as long as it isn't left submerged more than 4 or five days. This boat will be used only as a daytripper. On the wood surfaces I used Verathane Spar Varnish semi gloss. It finishes darker than clear. 2 coats. 1 quart. So hopefully this old boy will continue float for a few more years.
