I do wear my organic vapor mask while wet sanding now, but so what. The mineral spirits wet the sandpaper very quickly too - no need to soak overnight like you should with water. Most of the manufacturers are no longer wet sanding their finishes. They are using the 3M microfinishing films, dry. They start with 30 micron film and go up from there, all with a dynabrade or similar outfitted with a flexible replacement pad that allows them to get into tight waists and cutaways.
Cutaways still require some hand work.
Steve Henderson tells me he sands out a guitar in less than 15 minutes and then goes to the buffer. After sanding they go to red and white dry menzerna compounds. I said I would check out a finishing item it took over a month before I got to it so if someone else gets to it first post it. It must take an hour to level the finish even with the power sander. Let me preface this continued discussion by saying I haven't tried this yet.
