Hi again, as a new guy at buffing I need a respirator. Don’t want the cheap throw away ones. I have tried them and all I get is a sore throat and runny nose. Please someone recommend one to me that has replacable cartridges like the one I use for spray painting. About all I am going to buff is some small things,,,,,like a brass spitoon, some aluminum wheels etc. Any suggestions will be appreciated. THANKS!
