We have a wood front door with a clear finish. The problem is that the finish won't stand up to sunlight. The bottom third of the door gets sunlight but the top two thirds is shaded by the porch roof. About every three years or so we have to strip the door and reapply the finish because the lower third had discolored. We'd like to find a clear finish that will stand up better to ultraviolet. We're in the process of going through the refinishing process once again and are searching for a clear finish that's better than all of the ones we've used in the past. Lowe's has a finish that claims to have 100% more UV blocker but I'm suspecting even that may not be much better.
Has anyone found a clear finish that stands above the rest when it comes to exposure to sunlight?
