Phil,
You are right. Sounds like a brush or roller is the safe way to go.
Although there are instructions for spraying and a brief warning about
wearing a respirator on the POR-15 site - I found this warning regarding
isocyanates at www.zerorust.com:
In May 1984, the Occupational Health and Safety Branch informed autobody
shops that air-supplied respirators were required when spraying paints
containing isocyanates. Testing by the Branch has shown that air-supplied
respirators are also necessary when primers containing isocyanates are
sprayed. Even priming jobs of less than 3 minutes duration conducted in the
open shop will produce sufficient airborne isocyanate to present a risk of
over exposure to the sprayer and other workers in the shop. All types of
spray guns used to apply primers have been found to contaminate the open shop
if a separately ventilated spray area or spray booth is not used. When
spraying paints or primers containing isocyanates, the sprayer must wear an
air-supplied respirator which is approved by the U.S. National Institute of
Occupational Safety and Health (NIOSH) as Type C constant flow or pressure
demand.
Hey, let's not forget safety at home as we work on our cars!
