I have shot thousands of gallons of Lacquer, mostly "Satin". We used to buy as much as 50 five gallon cans, easier to poor and stays viable better, from SW. Was normally a month's supply.
Sprayed on most everything imaginable but never used it on leather. Used a lot of Neat Lac on leather. Don't remember it ever cracking. Sure had a strong odor. lol
Yes we sprayed from quart container spray guns. Used six different guns in spray booth equipped for three people spraying.
