Tim,
This is my third guitar that I am using the EM6000 waterbase. I really like it. I sprayed Nitro once around my house. The guitar came out great, but I had to finish outside. One day I sprayed and my wife had her office Window open. Yup! water base for me:)
I finished the last coats last Sunday, so I should be able to start buffing it out this weekend. I ended up with 16 coats on the back and sides with eight on the top and neck. I leveled every 4 coats. It only took a very light sanding the last two times I leveled. I really like my new spray gun. I got so that I could dial in the thickness that I wanted. No bubbles or drips but enough finish that it could level out. The pictures are from the next day after it dried. I did polished out the neck as I finished spraying it last week. It was perfect but I cracked the finish a tiny bit pounding in the bushings. Oh well plenty of time to slowly build up a repair with the WB lacquer.
