I use Feed-N-Wax on bearing edges and unfinished interiors.Mixture of beeswax and orange oil, I believe.
I do as well. Howards "Feed n Wax" was suggested by a forum member (James I think it was?) a few years ago. I used it on my 13 and 16 RK shell interiors. This pic is right after I put it on. These shells were very dry.
