Metal Polishing: Things You Need To Know

 

Metal polishing pads are used on metal surfaces to remove scratches and other defects. They do not work on plastic parts, so for polishing them, you need specialization products. As a rule, these are 3M or Meguiar's brand pads with added compounds that can remove deeper scratches than without using any compound. Sanding marks will remain after polishing by hand with those tools, but if you want to improve your results, it is better to use a drill-mounted buffer device.

With such a tool, a polishing pad is powered by an electric motor connected via a flexible shaft which makes working more accurate and faster. There are no corners that you cannot polish easier this way. It helps to remove deep set-in scratches some products leave behind even after hours of continuous work.

Types Of Metal Polishing Pads

There are different types of metal polishing pads such as circular, triangular and flat. Triangular pads are the most popular, and they come in a variety of sizes that can fit even your drill (8''-10'', 5'' square). The other types are circular and flat pads. The former is good for polishing round surfaces or curved edges like the wheel wells, while the latter is useful for cleaning and polishing flat metal surfaces like door sills, trunk locks, etc.

Some of those pad tools have flexible shanks that keep constant pressure on your part, so you do not need to hold the tool with your hand. This way, you will save a lot of time and get better results as there is no need to press down on your pad.

Preparing Surface Before Polishing It

Before starting polishing, you have to clean all parts thoroughly and degrease them with suitable products. It is necessary to remove all traces of brake dust, dirt, and other impurities that could interfere or leave ugly marks on your polished metal.

When all is done, and the surface looks clean, you are ready to go. The best way is to start with rougher grits (coarse) for removing deeper scratches while working your way down onto finer ones. Be careful not to overheat your metal as it can easily melt, and you will have to start all over again. When finished with that part, rinse it clean with water and dry it completely before proceeding with other finishes.
