Unsolicited Shop Advice?

A bit off topic of this thread but it needs to be said.
I do feel obligated to add to the cautions stated in the post above regarding spray painting and isocyanate dangers.

Isocyanates are a particularly nasty and deadly chemical to inhale. Many years ago, circa the mid 80's, as a working stiff, new to spray painting, I was totally uninformed by my employer regarding the extreme dangers regarding spray painting with paints containing isocyanates without a properly working, hooded fresh air supply setup.
A respirator with dual cartridges was better than nothing at the time, but when one doesn't know any better and the default, prevailing business attitude in the 80's was "do as you're told or hit the road," you do as you're told.
As a result, even 30 years later, I still suffer the effects of, in my opinion, what was a low exposure over 6 weeks of spray painting, to the isocyanates in the paint. My respiratory efficiency has never been the same.

In particular I was spraying the excellent Sherwin Williams paint, "Sunfire 421" onto "AlucaBond" structural panels fabricated for the roof lines, facades and support columns for a large, local shopping center in Raleigh, NC.
"Sunfire 421" is a 3 part paint mixed in a ratio of 4 parts paint, 2 parts reducer and 1 part hardener, hence the "421" in the name.

All one needs to know about the dangers of breathing in even small amounts of isocyanates is to recall the Bhopal, India disaster in December 1984 involving a Union Carbide pesticide plant. Check it out on Wikipedia if you feel like it as it a very sobering article to read.
Over 500,000 people were exposed to methyl isocyanate (MIC) gas and other trace chemicals as they slept. The toxic substance made its way into and around the numerous shanty towns located near the plant.
There were 3,787 "official" deaths confirmed by the government related to the gas release and the leak caused 558,125 injuries, including 38,478 temporary partial injuries and approximately 3,900 severely and permanently disabling injuries. Others estimate that 8,000 died within two weeks, and another 8,000 or more have since died from gas-related diseases.
