Ike,

I spray all types of lacquers; regular nitroceluous, pre-catalyzed, post catalyzed and conversion varnish. One thing I found to be very important if you are going to be spraying with a conventional gun and conventional compressor is to run your air line form your compressor to a seperate seperater/regulator, then a hose from there to your gun.
The seperater/regulator serves two purposes. 1; it will collect any water that’s in your air line ( that can screw up a solvent based lacquer finish as quick as anything and 2; It gives you a way to really fine tune your air pressure to your gun. You can leave the regulator on your compressor alone and run full pressure to the seperator/regulator and adjust from their.

I usually spray between 30 to 35lbs at the gun, but that really depends on your gun, how you have it set, what you may be spraying, and how you like to spray. Definitely the more presssure you’re spraying with the more overspray and blow back you will have.

My seperator/regulator is set up where I do my spraying and really don’t have to fool with it when it comes time to spray. I have a seperate hose I use for spraying and leave that attached to the seperator. All I do when ready to spray is bring my hose from my compressor over and quick connect to the seperator.

I drain my compressor often and I drain my seperator everytime I get ready to spray. In the summer, if I’m going to be spraying for any length of time, I make sure I drain every thing a couple times while working. You will be surprised how fast water can build in your compressor and lines if your compressor runs for any length of time.

You can buy those at HF, but they’re not that great, but I think your big box stores also carry them.

Just food for thought since I hadn’t heard anyone mention it before.
