We have a 1920's cabin. The original walls are redwood paneling - that is planks of redwood, milled (smooth), but with no other finishes that I can tell - perhaps some oil was applied years ago but nothing that you can see now. We'd like to refresh it. I've included a few photos showing some of the challenges especially in hight traffic areas. Has anyone done a project like this or know of articles on how to proceed? So far the advice I've found is damp wash it with something like Murphy's Oil Soap, light sand where it needs it and then coat it with Boiled Linseed Oil or Tung Oil - Poly Urethane or varnish being other options but I'd rather the oils since they seem easier to spot treat an area later if needed.
