Hello! I am taking on a project for a friend - finishing some wooden signs for her. The majority of them will be inside, but a few outside. They are live edge boards and discs, all the same species of wood.
My question is: If I use a spar urethane for the outdoor signs with the same sheen (satin) and a water based poly (satin) for the inside, will the finished look be the same? There are quite a few of the inside ones so hoping to spray with water based poly where I can. Thanks!
