When I was working as an A&P at Toledo Express, a buddy and I were assigned to spray the clear on two Piper Colts. They were behind a curtain and we went at it right away. Withing half an hour the manager walked in, grabbed us both by the arms and walked us outside the hanger into the November air without coats on. We were both so stinking high we were whoopin' and hollering up a storm. This was in just fifteen minutes or so, because we had not started spraying right away, what with needing to prepare the equipment and thin the dope. Think it's safe? No way, USE YOUR PROTECTION!
