Chrome removal from Bumper

I was thinking of sanding with a DA but I was wondering about the scratches. Sound like b they work!! Yuk!!

We did the bumpers on my sons car, just treat them like a body panel. If there pitted and rough, get them as smooth as you can with a DA, then let the primer fill in the rest. Shoot as many coats needed to sand smooth. Shoot the color.
