Whats that in oz ???? .. in the larger, but still smallish can on the SATA minijet 4, 250cc, which I think is about 5-6 oz max, I can shoot two acoustic bodies and a couple necks, plus get a second coat on one body and maybe the necks as well ...

what finish thickness did you get ?A quart should be plenty for 2 guitars and neck and then some.

I like Behlens Instrument lacquer and their vinyl sealer

I've never measured for lacquer (though I'm back to spraying nitro so I'll know soon enough) but when I'm spraying EM6000, I usually get 4 or 5 coats out of one DeKups small container...that's 9oz, so I'm probably spraying about 2oz per coat. A quart is 32 oz, and when I was spraying nitro I could easily get a full guitar out of a quart at about 10 coats, and most of a second guitar. That's before I switched to an HVLP conversion gun.

Wow....I can't even imagine spraying a 1/2 quart per coat...that's a massive amount of material.

How old is your gun? I remember those old siphon cup guns with their 25% transfer efficiencies, 75% of your materials were either in the filters or to be swept up off the floor.

I have finished 4 guitars with a gallon of EM6000 and still have about a half gallon left.

On my electrics there are a lot of rounded edges and details which waste material in order to guarantee coverage....but I do know that I use right about 40 fl. oz. of mixed material (nitro, reducer, retarder) per guitar to lay down 8 topcoats.

I'm experimenting on one guitar now....putting down only 6 topcoats. I think I'm totally safe considering I've never come close to sanding through with 8. If that works out it would be roughly a quart per guitar.

I seem to use more that most folks here. My detail gun has a 4 1/2 oz. cup. I can do a jumbo body or a med sized guitar body & neck without re-filling.
I do run the air at the highest recommended pressure for the gun, so I might be getting more overspray than I should. I shoot full wet coats when building up the finish thickness.

Yea but Howard they leave lacquer lying on the guitar like a blanket of pure liquid gold

Yes, and so will an HVLP once you get it set up correct and get your RTS mix right. And now your expensive materials wind up on the project, not the floor. Less VOC emissions as well.

I just finished 3 electrics that are on the larger side 14.75 lower bout. Went through 1 gallon of Mohawk. I feel this is too much and that I am sanding most off between coats. I need to change my sanding ritual, filler type and timing of sanding sessions I think. I am using a Fuji G-XPC 3. Interesting thread.
