Metal Polish Shop Says: polishing compound is typically sold in bar form and ranges from fine to coarse, much like sandpaper. Polishing compound is used to smooth and shine surfaces such as metal, plastic and wood. This compound also minimizes, or removes the appearance of scratches on surfaces by effectively “buffing” them out. Use polishing compounds with a buffing wheel for the best results. The best way to polish a surface is to first determine what type of polishing compound to use.
Select the appropriate polishing compounds for the surface. Some surfaces, such as aluminum, require only one polishing compound for a satisfactory finish. However, surfaces like brass, copper and stainless steel require several polishing compounds to achieve a mirror finish.
Different colors of the compound mean different grits.
Metal Polish Shop always wants you to wear a safety shield, skin protection and a respirator to protect yourself from the polishing dust and fibers from the pad that will be created.
Begin with the coarsest polishing compound that is needed. As you polish, move from the coarsest to the finest polishing compound until the desired shine is achieved. Remember that you can always move up in aggressiveness if you are not getting the results you want.
Spin the buffing wheel on a bench grinder, converted hand grinder, a dedicated multi speed polisher or electric drill. Gently push the polishing compound against the buffing wheel while it is spinning. Hold the compound against the buffing wheel until the wheel has a light layer of compound on it. Only a small amount of compound is needed. A little goes a long ways.
Different pads are used for different grits of compound.
Hold the item to be polished against the buffing wheel while it is spinning to apply the first polishing compound. If you are using the converted grinder or electric drill hold the buffing wheel against the object. Once the entire piece has been buffed, select the next compound, and buff the surface again. Keep doing this, moving up from the coarsest to the finest compound.
Once you have the desired finish on your object put some corn starch on a soft cotton cloth and rub it into the object. This will remove any black tags that may have been left behind by the polishing process. Some say this step is not necessary but Metal Polish Shop believes it is. If it makes the final out come just a little bit better why would you not spend the extra 5 minutes?
