we have a small pine board and batten cabin in NY, which is still in progress. We installed our board and batten in the fall, and plan to apply a wood preservative in the late spring, or as soon as weather and temperatures permit. What would be the best finish to use…that will last the longest, while maintaining as much of the natural wood look as possible? I realize that the wood will darken somewhat with the finish…but a natural tan, rather than a yellowy/orange is what we’re looking for.
