I finished my guitar over about a week. 4 days of spraying on lacquer in very fine coats, and letting dry then coming back and scuffing it every 3rd coat or so. By the end I had about 14 layers built up.
Then I started sanding up in to the VERY High grit sandpapers up to
1000 if I recall correctly. I really only needed to get up to about 800 before I could start buffing.Then I shifted to the buffing compound and the sponge apllicator. I cheated a bit in that I have a wood lathe. I chucked the applicator applied the compound to the sponge and rubbed it around on the guitar to do the initial application. I didn't want it being flung everywhere if I tried to apply it with the lathe running. Once it was spread around I turned the lathe on low and buffed it in. Using the lathe let me stand up and use both hands to steady the guitar as I buffed out the finish.
I wiped it down and strung it up. I wasn't happy with my stringing of the guitar. Since I knew I was out of my depth. I took my guitar to the local Guitar Center that had a guitar repair shop in it and let them do the final adjustments on string height and the bridges.
It plays very well and has a very mello sound.
