When I have cleared guitars I will dust a few coats on, saw about 8 coats, allowing a couple of mins inbetween to dry. Then I leave it a couple of hours and go back and spray about 2-3 wet coats and let it dry for a couple of weeks. Then I get to it with sand paper, wet, starting at about 600 and going up to 1200. Once done I apply 2-3 more wet coats and allow to dry for at least 2 weeks. Then I get at it with wet sandpaper from about 800 all the way through to about 2000, then I get polish on it and its done.
Obviously your waiting times will be drastically reduced if not removed all together as your using 2k.
