Balsa Wood Surfboards

What would you use to prepare a surfboard made out of Balsa Wood to get it ready for paint

Do you want the wood grain to show, like a vintage board, or do you want to paint it to simulate a fiberglass board? I assume the latter, but just making sure.

If you want it to appear as "wood", a mahogany stain would be appropriate for a really old Hawaiian style longboard. Probably no stain at all to simulate a later balsa board.  Balsa is extremely porous and will soak up the finish coat, emphasizing the too-large-for-scale grain. Many coats of clear urethane or lacquer, sanded in between, will fill the grain and make a fairly convincing job.

If you want to simulate a glass board, make sure it's very well dried to get it to shrink as much as possible. Oven drying is a good option. Personally, I would choose a two-part polyester or ( second choice ) urethane primer....bury it. When you sand it, be sure to re-prime any areas that get thin or have wood show-through. Wood moves and shrinks over time, and any thin spots in the primer will come back to haunt you.

Plan your work, work your plan.

Measure twice, post once.

Do you fellows know if 1/25 scale decals are available for 1960s era surfboards (i.e., outside of buying some of the car kits including boards)?

Mix talcum powder with clear paint, make it thick and brush it on. It sands easy. This is what I use to do when I built wood models.

Like Ed said Basswood would be better. Also to seaal it, if you have a airplane RC shop close by, there was a paint called Clear Dope that they used on the paper wings of the plane kits back in the day.
