Dave,
For what its worth, if you have space and the weather is good , I did most of my
sanding outside on sawhorses preferably with a slight wind. Still wearing
overalls and mask. It is an insidious product, however I did not suffer as you
have. So easy to become complacent with the use of it, especially if you are not
reacting to it.
I loaded a helicopter for one day, luckily, with 245T liquid solution without
wearing overalls, mask or gloves!!! This was 20 years ago however I have seen
the
results of it from a friend of a friend and the brain damaged caused.
Anyway, do as much of the sanding outside, less mess, more air, less
concentration, and better light to see your imperfections!!
Cheers,
Tim
