I have a 1 pipe steam radiator system. The radiators are ugly, and I am having covers made. The carpenter is using select pine, and wire mesh/grating on the sides and front. The top will be wood so I can put stuff on them. My question is, these will be delivered unfinished.
My covers are a combination of natural (stain and varnish) and paint. No problems with either one for the 55 yrs. they've been there. They all have vent holes (slots, actually) in the top and louvers on the front side.
