who said anything about a half mask? you should be wearing a full mask with A2 organic vapor cartridges with a compulsary particulate filter and a pre filter. limit your work to minutes not hours. and spray in a well ventilated area. if you have access to air supply respiratory system then by all means use it.
Panel beating shops in Australia use Sundstrom half mask when painting. so go figure. spray painting in general isn't healthy.
