painting timingbelt cover

[Fred Munro]

The primary toxicity in Imron is from the isocyanate in the hardener.
Isocyanate is present in many two-part single-step auto paints. Forced air
breathing apparatus is recommended, although you can get away with a very
good cartridge respirator for small jobs in a very well ventilated area.
Spray is the most hazardous form of application since it creates an airborne
mist. Brush application creates a bit of fume but is nowhere near the
problem of spray application.
A quicky 10 second shot with an air-brush in a very windy carport using
isocyanate-based paint without a mask (hey, it's just a little touch-up on a
very small spot - no problem) can leave you sick for three days. Don't ask
me how I know this....
