And of course the final result is dependent on how good the underlying wood was prepared, and that is excellent as well. After seeing this guitar, I think I may set mine on fire!
HA!! Don't burn it! Thanks for the compliment. The finish ultimately turned out great, but it took a while to get there.
Here is what happened to the finish:
I thought my prep was good, i.e. flat surface to apply finish to. It was either not flat by the sound hole, or I simply sanded poorly. I suspect it was the former. In any event, I was doing my wet sanding of the finish and got a small sand through on the rosette. I applied more lacquer, and in my infinite wisdom, decided that spraying some retarder on it would help it level better. It did, but you have to keep in mind that the sound board is not level, it is a dome. So when the retarded did it's thing, the lacquer, new and old, leveled itself such that I had almost no lacquer in the center of the SB, and a ridge of lacquer near the edges of the SB. GAAAHHH!!
So I had to sand that all smooth again, then reapply more lacquer on the entire sound board, and then begin wet sanding again.
Fortunately for me, I realized that the compound I use to polish the lacquer will remove the sanding scratches from 1000 grit paper. So I only had to sand with 600, then 1000 grit, then hit it with the RO buffer to bring out the shine.
As an aside, I read all of the time how guys will wet sand up to 2000, 2500, or higher, then use a polishing compound that actually brings the finish back to some lower grit. For example, people who use a buffing arbor with Menzerna compound. The medium grit compound is equal to 800 grit sandpaper. Why would you sand to 2000 grit, then go backwards? You would not do this with actual sand paper, would you? Sand through the grits to 2000 grit, then finish off with 800 grit after all of that work?
Anyway, I now only sand to 1000 grit, then begin polishing. This new process has saved me HOURS of sanding. Hours. Of sanding. Sanding. I hate wet sanding. SO there is your helpful tip of the day from me.
