Has anyone done this?   My sprayer (Wagner Project Pro 119 - a 720W, 200 bar, powerful machine) says nothing in the manual, but some "details" seem to insert an extra "and exterior" here, which is not in the manual:   "Lacquers and glazes containing water and solvents. Lacquers, oils, solvents, solvent, PVC lacquers, pre-lacquers, primers, fillers and anti-corrosion paints. Interior and exterior dispersion and emulsion paints. Also suitable for many types of thicker paint.".
