If you re-read my posts you will see that most of what I said was in the form of questions not out and out statements. In fact, I specifically ASKED why a 2 stage mask wouldn't protect against lead particles and other posters, with no condescending attitude I might add, answered my questions. Hell, even when you quoted me you included my QUESTIONS.
I might suggest to you to drop the condescending attitude and instead of the snide remarks, take direction from the other members of this board and answer questions, and discuss the topic at hand like a professional.
You remind of the fuckwads at Lansing and other places when I was a kid. I'd go in with some questions on how to do something and they'd walk around like their shit don't stink and how dare I bother them with my silly ideas. Well, glad you feel so superior, I just hope one day, when you discover something that you don't know everything about, someone WILL treat you the same way......
