The type of media used in this process can change depending on the desired finish. A range of results can be achieved by altering the type of abrasive and blast pressure applied. The finish can also differentiate by using the same type of media but changing the grade. For example, a fine glass bead will produce a more polished, satin finish which is often used for an aesthetically pleasing surface. Alternatively, a heavier grade of glass bead will produce a rippled effect which is good for stress relieving on metals etc.
