Again, Imron is dangerous stuff. Had a pilot at the field sent to
the hospital for two weeks for not using an aspirator while spraying in
a hanger. It can be absorbed through the skin and disrupt the nervous
system. Almost as bad a nerve gas.

I do believe you mean respirator, not aspirator.
Specifically, a pressure hood.
No part of your body should be exposed when using IMRON.
That means wearing a pressure hood, set of coveralls, gloves and boots.
THEN tape the wrist and ankles to seal.
