I installed an island countertop made from mahogany slabs about two years ago. I finished it with walnut oil which we renew about every month. The slab turned a beautiful deep red which my daughter loves. Now I am about to build her a hope chest from mahogany.
Is it possible to use the walnut oil, allow it to dry and then overcoat with spar varnish or poly for durability?
Thanks for the input! I attached a photo of the counter.
