I am working on building several sets of shutters and the finish will be a low sheen acrylic enamel sprayed on. I tried an N95 mask I had but it did nothing for the vapors. I had a P100 with organic vapor cartridges respirator that I used previously for things like this but the rubber parts dried and cracked. I have not been able to find a replacement respirator for use in spray painting due to current events. Is there an alternative or should I be looking in places other than the usual home centers and online stores?
