The mask will work if the spray is a pump. However when it is an aresal can type the chemical that is used to create pressure for the spray to come out lingers in the air. It makes the air so thick I can't breathe. I was at a LQS when the owner sprayed for me when I was making a bag. I waited outside. When she was done I came in and about died. It felt like trying to breathe through water. I had to avoid that area for a long time and I held my breath a lot until I got my bag finished. Even while I was working with it it was still effecting my breathing. When I come across a project that requires me to use s basting spray, I am sure I can come up with a way to adapt. I know a lot of people swear by them especially on small projects. Besides, what are DH for? But I will keep the mask in mind. If I remember correctly, I think there are masks that will filter out chemical ordors too. They are pricey, but if I share it with my husband's car hobby he might go for it. You never know?
