Once the first coat has dried completely (usually in 6 to 8 hours), sand with a fine grit sandpaper, removing all bumps and imperfections (see Fig. 5). Do not be afraid of scratching up the first coat of finish during this process, the next few applications will cover any scratches you create. After you have sanded the entire surface, dampen a cloth with paint thinner and wipe the sanded surface. This may leave a light film on the surface which will disappear with the second application. Remove the brush from the thinner and shake it out a few times to remove any excess (see Fig. 6). The remaining thinner in the bristles will replace that which evaporates from the varnish can while open. Often when doing a large project, I find that my brush starts to stick as I am working.

To add a finishing touch, use No. 0000 steel wool dipped sparingly into a can of cabinetmaker's wax and wipe with even strokes along the grain (see Fig. 8). The steel wool will remove small imperfections left in the finish by dust particles and will also embed the wax into your finish. Be careful not to rub too hard, especially near the edges. The wax will also prevent tho steel wool from cutting too much into the finish. After several coats, use a clean, dry cloth to buff the surface (see Fig. 9). You will find that after following these instructions your next project will achieve a beautiful hand-rubbed look. October, 2000 49 even brush strokes. a fine grit sandpaper. exce&6 thinner. Fig. 7.
