Paint spray contains harmful chemicals such as isocyanates, solvents, and paint additives.
Painters at many auto shops use only HVLP spray guns when refinishing cars, without sacrificing the quality of the finish, even for top coats. Of course, you'll need to make some technical adjustments to your pressure settings and spray cap when converting from a conventional spray gun to an HVLP spray gun. But once you do, you'll find that HVLP spray guns are relatively easy to use, reduce overspray, and produce a high quality finish. Talk to your jobber, paint distributor, or equipment supplier.
