I didn't use Flexio but I was using Wagner 518080 Control Spray Max HVLP with acceptable success (if you aware about overspray issues). And you need to tint latex paint otherwise it sprays unevenly (orange peels). I used with latex paint and watebased poly. I wouldn't try to use it with oil based things. Likely you will not be able to clean the gun. Also you need to learn how to use it :) It's not so obvious how to choose air-flow and how it affects paint volume.
Bottom line I will leave it for outside work and buy something better for woodworking.
