My 1968 Sunfish was acquired at the local dump. Now that I know that it floats and sails well, stays dry and is enough fun that I will keep it, I am getting started on making it look better. The bottom was painted with a brush in something that looks like red primer from a car. I plan to strip that and have no idea what is under it. Is there a "best practice" in refinishing. I've never used gelcoat but am willing to try if that is the best option. I will not be racing at all. The boat is used in both lakes and the ocean. By the way, I built the PVC dolly that has been describes on this forum. With the same set of ramps that I use for my snowblower, I can get the boat into my Chevy S-10 pickup single handed and lashed down in about 15 minutes. Boat and dolly wheels came from the dump. I've spent about $75 on varnish, screws, inspection ports and the pipe for the dolly and get a nice a little boat to kick around in. Lots of a great ideas have been found on this site. Dave G.
