restoring finish on exterior ceiling
I need some advice on how to restore the beams and planking that extends from an interior ceiling outside to cover a deck. (There are pictures on the link at the bottom of the page.)
The condition of the interior wood is fine, but the exterior has gotten weathered (25+ years of neglect by previous owners.) It is sheltered from sun and rain but there may be some moisture damage from before they replaced the roof.
How should we go about the restoration? We were planning to sand off the remains of the old polyurethane and then stain to match the interior. Can we use an interior oil-based stain and then cover it with something like "spar" polyurethane? Are there better products out there? What do you recommend?
