I need to paint the interior of the boat (now open, without deck) before I transport my Snipe to a local area boatbuilding school for restoration work. The interior has been sealed with tung oil sealer, and sanded. I will be painting the interior with oil based alkyd enamel. Do you think it is OK to apply the paint directly over the existing sealed surface, or should I apply an oil-based paint primer first?
I asked the Antique Boat Center (Cincinnati, OH - on Facebook) what they do for finishing the interior of the wooden Chris Craft, Century and other classic inboard runabouts that they restore. They seal the interior with CPES and then paint with oil-based alkyd paint. I thought that maybe I could follow a similar process with my Snipe. I'd rather not go to the extra step of applying the primer if it's not really needed.
What are your recommendations - paint OK directly over sealed wood, or use primer first and then paint?
