I am doing a few things to spruce up a house I will sell. 1953 craftsman. Some of the window sills are very tired. Failed finish, missing in some spots, discolored or worn. My plan is to do a little light sanding, which will leave most of the lacquer in place, and then apply a thin coat or two of new lacquer. I feel pretty confident the original finish is lacquer.

I am not trying to refinish these sills. Just make them look a little less distressed.

I have thinned polyurethane before and applied using a lint-free paper rag (from an auto body shop) with good results. I wonder if this is the technique I should use to apply lacquer.
