I'm reaching deep here because it was 6 years ago when I painted my 1980 C22. The temp was 55 to 60 degrees at the boat and the paint was 70 to 75 degrees at the start. The boat was in a garage. I used single part paint and used one of those double bi-zillion watt shop lights and the lights actually warmed the hull alot prior to the paint pass. The hull paint was a very dark blue and the deck was ivory/beige. We tried to recreate the paint and hull/deck color of our Island Packet 38 from a earlier life. We primed the hull with 2 coats primer and then lightly wet sanded (600 grit wet/dry) and applied the last primer coat. The last primer coat was 1/2 dark primer and 1/2 paint color. We rolled the primer coats vertically with a 6" foam brush and horizonally tipped the last coat with a 4" dry brush. We tipped after 3 vertical passes or about 15". NEVER, NEVER re-tip older vertical passes. This is a 1 shot item. We used 1 and 1/2 qt primer and 1qt paint. We had an extra qt of primer for the deck so we might have used some of that on the hull. Can't remember. Must be the paint fumes.
We had 3qt. of dark blue for the hull and used it all. We used a 6" foam roller and tipped all color coats with a 4" high quality paint brush dry. Don't ever use the tipping brush for painting and clean it offen with a rag soaked with your paint thinner or solvent used to clean your equipment and keep it as dry as possible. The cleaning stuff that the paint manufacture tells you to use with the paint. We never dipped the tipping brush in the solvent we just used the dampened rag and then a dry rag. We lightly sanded the hull paint after the second coat with 600 w/d and applied the last color coat. The outcome was STUNNING! Since we sail fresh water and trailer launch each time we don't use bottom paint. We painted the bottom the same color.
The deck/cockpit was 2 coats primer and only tipped in the larger areas. Also only the larger areas were sanded lightly after the second coat. Then we color painted in the same manor as we primed. We used 3 coats in higher use areas. and 2 in the others.
We preped the hull and deck by using marine/auto body filler in all scratched areas, divots and holes and then sanded with 120, 220 and 400 w/d untill they were fair. The hull will show any blems but the deck doesn't. It is worth all the effort prior to painting if you want a nice job.
It seams like a lot of work but isn't bad IF you have the boat at home. It's not a job to be done in a land far, far away.
Good luck, Ray
