Media blasting is basically a form of rough abrasive blasting where sodium bicarbonate pellets are shot against a hard surface with compressed air to form a smooth abrasive. It's a milder form of rough blasting than sandblasting. The earliest use was on the preservation of the Statue of Liberty during the 1980s. It was also used on an aircraft that crashed near Hoover Dam, creating a huge hole in it. The media blasting process itself was later patented by Dew Laboratories, who later gained the rights to market and manufacture this product under the brand name 'Blue Sky'.
There are many different kinds of trusted media blasting products, including shot peening, which is the most popular. It involves an electric-powered spray gun spraying a mixture of steel balls at an existing smooth surface, causing the material to be roughened. It can either make the existing finish look better (making it look like it's been sandblasted) or completely remove any existing finish. This is used for polishing metalwork, like a bolt handle or doorstops.
Number one media blasting is the use of fine abrasives, which are mixed into a fluid, fired, and then shot at the target surface. Abrasives can be mixed from a wide range of materials, including metals, plastic, and ceramics. The shot peening process is similar, except that instead of liquid being shot at the surface, it's air which is shot at the surface. The air must be directed at a very high velocity to produce a smooth surface effect. The air also has to be at a low velocity, so that the material it's shooting at doesn't go through the gun and bounce back into the air.
A popular media blasting product is aluminum oxide powder. It's a powder that's mixed with water. Because aluminum oxide powder is a very soft compound, it acts as a liquefier, meaning it can be shot against a smooth metal surface without damaging it. This product is widely used in a wide variety of products, including dent repair. In the process of getting rid of dents without damaging the surface underneath, aluminum oxide quickly bounces back into the air, leaving the area relatively clean.

Another common media blasting product is abrasive grit blasting equipment. In the sandblasting process, a cylindrical drum containing abrasives is shot at a moving object. These cylindrical drums come in different sizes, depending on what kind of material the user wants to sand: coarse grit (such as aluminum) and fine grit (such as brass). A fine grit abrasive will cause the surface to become imperfect, while a coarse grit will make the surface smooth and shiny. In addition, it adds some circular movement to the process.
One final type of media blasting product is chemical stripping. Instead of blasting away the surface, chemical stripping machines will chemically strip old paint or rust from it. If you need to remove paint or rust from an existing finish, this might be a good choice to consider.
