    I have a "T Partscaster" project to finish, mainly the neck. Getting the nut set perfectly square & pretty is always a hair puller, & patience is king.

    I also have to sand, stain & finish the neck, (rosewood on maple, Huge; Baseball Bat Thick.) Main question:
    I have a couple quarts of Watco Lacquer, gloss & semi. If you look at the MDS sheet on the stuff, it's Nitro.

    Has anyone thinned & sprayed this stuff? If so what mix ratio (thinner & goop) & what pound pressure on air supply? And/Or, does the rattle cans of Watco dry hard. (Deft does not.) I do have a touch up gun, compressor, but I don't have a garage. (Never spray outdoor in warm sun. Lacquer dries before it hits the neck.)

    I even thought , a soft brushed on lacquer may work, with 3000 grit wet sanding when fully cured. I'm looking for a worn, gloss finish.

    About 40 years ago with a buddy, we custom painted my 62' panel truck & it turned out pretty darn good. I've also "Rattle canned" a couple necks.

    Thank You. All is well, and I'm not comfy over on another site.

    I mixed it 50/50 w/thinner and thought it sprayed fine. For the record, I used an airbrush so I probably
    can't help with the pressure thing. I've seen lots of folks that aren't fans of the stuff, but I found that
    it sprayed fine, dried in a normal amount of time, and it's seems to be fine as it comes to hardness.
    I've also never had an issue with the Watco rattle cans. Then again, I never experienced much of an
    issue with Deft either. I always use "Gloss" and the humidity is ALWAYS high down here in the swamp.

    Used plenty of watco on furniture over the years. To soft for a proper guitar finish IMHO

    I would never contradict Brians's level of expertise and always look to him for any possible tips and advise....that said, maybe I have just been lucky but have done 3 builds with Watco gloss rattle can and had great results.....in all fairness I did follow the "rule of threes" but actually did 5 days worth of spraying and left them for 6 weeks to gas off before buffing. Last build I thinned the canned Watco as Emoney did but had better luck with spray cans :) Likely my lack of talent not a reflection on the lacquer....anyway, FWIW

    I've used the rattle cans extensively and I can attest that it does indeed cure extremely hard. The guitar in my avatar is finished in Watco. The finish is hard as a rock.

    I have a quart can that I will eventually get around to using in a spray gun. I'm not sure on the mix ratios off the top of my head, but maybe this will help.
