Never had that happen either. Supposed to wear a dust mask when buffing. I never used to but I have been lately since I noticed an increase in coughing and irritation after a good buffing session when not wearing one. Earplugs too. Huh?
Yea I should use a mask never have when buffing. Using an air buffer that I bought not long ago for the first time and real quiet so ear protection I don't think is an issue.
