Mechanical stripping can be performed in any manner using power or hand tools to remove the paint. My preferred method is to use a grinder with a wire wheel attached, but also use wire brushes, sanding disks, and scrapers depending on the parts shape and size. The wire wheel though, allows me to remove rust and paint in one step quick step and will remove all coatings to the bare metal. One word of caution though. Using a wire wheel to remove paint and rust does not adequately remove the rust from the metals surface. If you were to paint over the top of the wire wheeled metal without any further rust abatement, it is going to rust again in the future. In order to properly prepare the metal for painting all traces of surface rust must be completely removed or neutralized before primer is applied.
