Manufacturers answer that either there are problems in technique, the machine is too small for any decent use, or quite probably, there are some materials some machines can't handle. Lyster also had a problem with heat. Some turbines can get so hot, the paint begins to set up as it's being atomized, and it's dry before it hits the surface. I fogged up a whole credit union one night. That's when I went back to electrostatic.
Manufacturers admit heat can be a problem.
They recommend a different solvent to slow drying time. Others have placed heat dissipators on their machines. Although sometimes the heat pays off. Lacquering in cold weather is a plus with HVLP, according to Dennis Moffitt. With the hot air, as soon as it's out, it's setting up.
