 After sanding off all traces of paint and primer,sand the surface smooth with 80g on the random orbital sander to smooth out 40g sand scratches as they will show though the finish, remove dust with a blow gun and a clean cloth. Don't touch the metal with your skin; it will contaminate it. Immediately spray on etching primer to keep ambient moisture from contaminating the panel. Always wear a respirator when spraying etching primer.
-====Wire Cup Brush====
-A wire cup brush will take paint off rapidly, almost as fast as 40 grit sandpaper on an orbital sander, when the wheel is mounded on an angle grinder. The wire wheel will not scratch the metal as deeply as the sandpaper, making prepping for primer a bit easier.
-Wire cup brushes come in two basic types - with kinked wires, and with twisted (or knotted) wires. Although it seems like the twisted wire would be faster, as it is more agressive, the kinked wire actually will strip faster, as it is more flexible and can make contact with a larger area of the panel with every pass of the tool.
-Wires will come loose and fly off the wheel during use. It is recommended to wear a face shield and thick clothing when working with one to avoid injury.
