Even something as "stupid" as wearing an appropriate mask can save you years of aggravation. Just ask a guy that welds galvanized steel without one. His lungs are AFU, and he has about 30% of his lungs left.
I even wear one grinding. Amazing how much crap it keeps out of your nose. I didn't wear one Friday for 20 minutes, and I'm still blowing black crud from my nose.
Try to retain OEM equipment. Aftermarket eyes, lungs, etc. just aren't worth the price.
