Can the Wagner HVLP paint spayer work with interior metallic paints

I believe this paint is water-based. The Control Spray Double Duty is designed for use with thin materials such as oil-based primers, enamels, stains, varnish etc. Most water-based paints will be too thick to be sprayed with the Control Spray Double Duty. I'd recommend looking into our Flexio 590 which is very similar to the Control Spray Double Duty, but is stronger and able to work with most water based materials.
