I just bought another - I had an Iwata hp-bcs but it’s a siphon unit, good for lots of paint but not for switching colors or small jobs so I bought another Iwata hp-cs… it’s a gravity feed, I really like them, they haven’t been too hard to adapt to the learning curve…. Just gotta figure in the compressor as part of the requirements…. I use the Harbor Freight 3 gallon unit for mine…. And I do as Brian suggests - glue the photo etch on and then paint, unless the photo etch part is supposed to be a different color of course….
