what and where are the documented health outcomes from painting with urethanes and hardeners? I am long retired, but over the years I have painted probably over 200 cars and trucks with urethane and acrylic enamel with hardeners. I was painting when the first paints with hardeners were offered by Dupont and Sherwin Williams, paint suppliers we used here in SW MI. I almost passed out once when using the early urethane with iso hardener back around 1975 or 76. I am still planning on painting my 55 Ford F100 this summer with base coat, clear coat and a HVLP gun. I paint in a very open area and probably over several days as it will be painted disassembled and in stages. Back in the old days when painting with a mask in a spray booth, I would usually have a overspray pattern on my face around the mask. The way I paint now, that does not happen. I know there are risks in painting this stuff, but no one seems to clearly state what they are. I am a fairly old guy, retired for over 15 years with many or most of the health concerns/complaints of people my age, mostly arthritis and mildly decreased memory.
