I am looking for the means to preserve cedar planks on the ceiling against dirt, oxidation and graffiti. Originally supposed to be painted but once installed everybody wants to leave it as is. It is the wooden landmark subway station control house under care of MTA and their goal is to have it maintenance free or no more difficult than maintain painted surface.
