Primer for Wood for oil-based Rustoleum?

[Berdink]

I've searched these forums extensively, Rustoleum Oil based enamel is often recommended even for wood - even for under water - if I'm mainly in freshwater. In fact, I have no reason or desire to take an 18 footer into salt water. But I'm not finding what to use for a wood primer. Rustoleum has an oil based primer, but it says for metal. Anyone do oil based rustoleum on wood? and what Primer did you use?
It's for an the exterior transom plate over my pitted aluminum transom skin.

I would use the old timers wood preservative.

Options for water sealing wood

I'm just poking around for some options for waterproofing-or at least water-resisting wood. I'm rebuilding the gunnel panels, engine doghouse, and cabin of my boat next. Everything is above the deck. I'm looking for an effective-cost conservative method of sealing up the plywood panels before...

or I would thin out the primer with some acetone and get a few coats on prior to the paint.

if the skin is really pitted, i would re-skin it. did someone use pressure treated lumber as the transom board?

Presumably the transom board is wood? Rustolium does make a primer for wood, although you could use brand any oil based primer for wood.

I am not sure I would use paint on any underwater wood. Paint just sits on the surface of the wood and blisters too easily when exposed to moisture.

I would use an oil based outdoor stain for color. Semi solid or semi transparent are best. They will penetrate and protect the wood. Then several coats of spar urethane to seal it up.

No PT, they used a stainless steel overlay. I posted about it here in my thread ''67 Holiday 18' - Make it Usable' https://forums.iboats.com/threads/67-holiday-18-make-it-usable.753826/post-5741551.

I'm definitely using OTF on the transom itself, but this is going to be a transom plate at the exterior between the motor and the skin - over the area where the SS was. Do you think OTF would be good under water?

I would re-skin with 5052 myself. or I would get a sheet of starboard for $100 and use that.
