Hello. Been a while since I posted. Recently I painted some hemlock window trim and baseboards using SW ProClassic (waterborne), with mixed results, but overall I like the finish. Then I got to thinking and then reading about clear coats, and now I'm wondering what the general considerations are for when it might be a good idea to finish painted trim and cabinetry with a clear coat. What would you say is the primary reason for finishing with clear? Does it add strength and/or endurance to the finish? Thanks.
