Paint Removal Cleaning Disc 7"
Product Review (submitted on May 11, 2011):
This disc is the answer if you have paint mixed with surface and/or mildly penetrated rust. It takes the paint and rust out, but does not damage the metal. It also leaves about a perfect roughness for an epoxy primer. In my experience, one of these discs will last for about 3-4 SF of paint/rust removal.
