paint fumes are no joke, i've told this anectdote before, but...
years ago i was painting and like a dumbass, somehow, i managed to spray directly into my face as i was breathing in. Well, later that night i was at a party, and i blacked out and had small seizure. Somehow nobody noticed, or they just thought i was drunk. Anyway, for months after that I had horribly painful heart palpatations. So painful they would literally bring me to my knees. Also, i would have muscle spasms on one side of my face. Horrible, use a resperator. And don't be retarded like me and spray your self in the face.
and, dust maskes do nothing.
