I have had a Primus smoothing plane and a block plane from the 1980’s. On a whim, I recently bought a Primus jack plane companion because it has a lignum vitae sole. It must be new-old-stock. The bodies of the smoother and block are pear I think. The new jack is beech. The fit of the new plane is excellent and it arrived, as all Primus planes do, very sharp and ready to use. The difference is the finish. The finish is a bit rough. I want it to feel as smooth to the hand as its older siblings. What treatment would you recommend? Steel wool and Johnsons paste wax? Pumice and linseed oil? Wet sand with auto body paper and rattle can lacquer? I suppose the finish on the jack plane is lacquer but haven’t tested with solvent.
