[AT] respirators and Isocyanates (Urethane paint)

[oldiron62 at gmail.com]

  I have a air compressor that was used for diving in 15-20` water. It has a 
5hp honda engine on it, and im willing to let it go. If it supplied 
breathing air for underwater work, it should work great for painting, 
blasting >>
Anyone interesred contact me offlist.
