Preval

I’m painting my baby girl’s headset to match mine when we fly in the helicopter. I thinned the paint and think followed all other instructions, and the Preval paint sprayer almost covered her little headset, and then it clogged. That was ok because they need to dry and then be painted two more coats so I went to the store and purchased two more Preval sprayers. I strained the paint and thinned it some more, and both of the Preval sprayers immediately clogged and I couldn’t even put on a second coat let alone the third and final one.
I disassembled the three non-​working Preval sprayers and cleaned the tubes and bleed valves and removed the strainer, and it was all a waste of time and money they spray nothing but the gas that comes from the tube.
Preval «amazing spray system» zero stars, and if a product is difficult to impossible to use why does the company market it? And it is marketed widely one Preval sprayer was purchased at Home Depot and two at True Value Hardware.
