Thank you!!
I have to say, I have saturated this transom with the old timers formula and let it dry out for 48hours. Then I put two coats of spar urethane on the whole setup. This transom looks AWESOME!! It is going to keep water out for a lonnnggggggggg time!! What a great formulation!
I have read a lot of info on the 1:1:1 ratio, and this is the only place I have found that recommends 2parts mineral spirits, 1 part linseed oil and 1 part spar varnish/urethane. Either way it sounds like this has been a go to for natural wood finishes for a very long time, and I can see why!!
