I am replacing the transom and seats in a 16 ft runabout and was wondering if I should paint or stain the wood to protect it from moisture. I am using marine grade plywood 3/4 inchx2 for transom and 1/4 inch for seatbacks.
Definately protect it. Stain won't do the trick. You can coat it with epoxy or at least paint it with a good weather resistant paint meant for outdoor use. Make sure any through bolts in the transom are very well sealed. Good luck...
Wait, Wait. Paint it with epoxy, then a good grade exterior paint over it. Epoxy is UV sensitive, and wont hold up long in the sun unless it has a barrier coat.
West systems is fine, look on the internet for the best prices. You can check Iboats, I like USComposites.com myself. A good polyurethane paint would do the trick by itself or over the epoxy. My center console on my boat is wood, only painted with polyurethane paint and it has held up just fine in the elements. I have three coats on it.
