Applying a Mirror Finish (by hand)

Step 3 Initial Wet Sanding

First, the surface of the paint or clearcoat must be sanded to remove any imperfections (deep nicks and scratches must be filled before lacquering, however.)

Soak the sandpaper in the soapy water. Use your sponge as a sanding block. I cut this small one from a larger sponge, and this is one of several cut.

Use 400 or 600 grit wet-dry paper. Be especially careful during this step, as sanding through the finish is easy with the coarser paper. Preparation (sanding, filling, painting), and multiple coats of lacquer help to insure the finish is free of woodgrain texture. If grain remains in the piece, sand with the grain.

Exercise care when sanding hard edges. It's very, very easy to cut right through the finish on a corner.

Wipe the work down often, first with a damp cloth, then a dry one. Inspect visually. This will help gauge your progress.

Sand only until any uneven surface texture is removed.

Note: If you drop the sponge, sandpaper or wiping/drying rag on the floor, START OVER WITH A FRESH SPONGE, SANDPAPER, ETC.
You're likely to scratch the work, if you don't.
