The cans can still sputter and "spot" at times. I figured out it was my lack of full nozzle engagement during my push of the button. It allows the propellant to "spurt" the finish due to not enough atomization. Layman's terms: the finish will build up a bubble of material at the face of the nozzle under less pressure push and then when you fully push the nozzle fully, a "glob" goes on the stock and leaves an imperfection on your already smooth surface film. I hate it when that happens and have been using an aftermarket spray can gun handle to combat that.
