I'm awaiting an answer from 3M on the mask spec I want - I'll let you know what they say. As for spraying AwlGrip or Awlcraft, I've sprayed both - I make sure that I have created a draft with an industrial fan sucking air from my spray area to create a good draft and I stay "upstream" from my spray at all times. I have also rolled and tipped and the results are always surprisingly awesome. But, I still would rather spray !
Those paints are not to be screwed around with as the affects can be permanent.
I just had a really bad bronchial cough for 1 month after heavy fiberglass grinding using a mask but also being in my covered boat without a mask breathing in kicked-up fiberglass dust particles. Scared me a bit. I read up on it and although your body will clear it - it ain't good ! In the same read, I read about the similarities and THANKFULLY differences with asbestos - and how that nasty stuff penetrates your lungs - scary !
Be safe !
