After I have filled the pores in the wood and detailed the instrument looking for any defects that need to be corrected, I set up the paint booth and start to apply the lacquer.  The process involves applying several coats, and then sanding down all of the high spots and then repeating the process.  I put a balloon in the hole to keep the spray from getting on the inside and I use a rotating stand so I can easily get to all of the parts of the guitar.

Here I am sitting outside on my new deck working on the neck.  Each layer of lacquer fills in the low spots and eventually the surface becomes very smooth.  This process is called leveling because eventually the surface becomes leveled out.  The number of layers is somewhat indeterminate in that I am finished when the surface is level.  I work to keep the finish as thin as possible, but I want enough so I don't sand through the finish as I am leveling it.  I will take a wild guess and say that after the leveling process and the lacquer has cured that the finish may be 1 or 2 mills thick.  Only a guess though.

After the surface is leveled off to my satisfaction I begin the polishing process.  This involves using progressively finner grits of sanding cloth until the size of the scratches is smaller than the wavelength of light, approximately 400 nanometers.  In the final step I use a buffing wheel that removes the last bits of haze.

Now I am preparing to remove the lacquer where the bridge will go.  This is a very delicate and precise process.  I use Dremel tool with a router bit to remove the very thin layer of lacquer and then sand the surface to make sure there is a good gluing surface.

Everything goes well and I have removed a footprint that exactly matches the bridge.

Here I am gluing the bridge on to the top of the guitar.

The frets get a final dressing to make them level and shinny.  I put a protective cover on the guitar when doing this so I don't mar the surface.
