Richard: I have a very basic, first-generation Aztek that I've painted with for about ten years. I'm fine with it-- it does what I need it too, and with easy cleanup and minimum fuss. I very seldom get clogs with acrylic paints if I use a metal mesh filter in the intake tube, and keep the nozzle wet with a shot of Windex any time I set the bush down for a few minutes. But I do keep a second acrylic nozzle on hand for those occasions when clogs happen. In the event of persistent clogs, I have always been able to unclog the nozzles with a simple overnight solvent soak.

I can't recall getting a clog more than once or twice with slower-drying laquer-based paints like Scalecoat. I'm still painting those with the original nozzle. Best,
