THIS MORNING I sanded each instrument with wet and dry 600 grit paper on a flat sanding block to grind off any lumps, high spots and problems on the shellac finish. To keep the paper from loading up you must dip it in water with a drop of detergent in it. Washing the paper from time to time keeps it cutting. Wiping the ukes dry you can then start applying the final coats of French Polish. I got the first of the finals on today.
