Could someone advise me as to which nozzle would be best for: 1) enamel paint (ModelMaster) 2) Acrylic paints and Future Also, any info on recommended PSI's would be helpful. Thanks, George |

George, your brother can find the HS manual here. The nozzle size and compressor pressure depends on the paints used. Modeler tends to thin the paint pretty thin. The H1 nozzle and 25-30 psi pressure will be a good starting point. The Paasche HS is an external mix AB and needs higher pressure than what is usually mentioned here for internal mix airbrushes. Use lower pressure only for special effects. If he paints larger craft object using craft type acrylic which tends to be much thicker, the H3 or H5 nozzle with pressure up to 45 psi can be used. Try different pressures until he gets good atomization of the paint and no excessive run. From the Paasche manual: OPERATING INSTRUCTIONS: Approximate Working Pressures: - 20 lbs. or Less: Stipple and granulated effects, pressure will vary with viscosity of fluid.
- 20 to 30 lbs.: Medium consistency water colors, inks & dyes.
- 30 lbs. or More: Heavy fluids, acrylics, reduced lacquers, varnishes, paints or ceramic glaze.
