I have a 1903 house with a "car siding" ceiling on the front porch that needs refinishing. There is no paint on it. Natural color, kind of dark and looks very "dry".
I don't know how to refinish this. And I don't know what product to use. Laquer, Varnish, Polyurathane? If it was originally done in one of the two former products maybe I don't want to put polyurathane over it?
Thanks for the advice.
