Just picked up a 69 front bumper for $25 for my project. Its beat up bad. I wanted to sand it and paint or wrap it. Ive chrome is toxic but i seen so many people sanding thier bumper. I would guess not all bumpers went threw the same plating process. But for the time period of my bumper i would think it was one of the harsher applications involving lead and what not. How qould i go about sanding witout killing my health?
