Shot blasting is a process used to clean surfaces back to the base material.
The process involves a nozzle with a high-pressure airline to deliver various types of media, or shot, at the part. This is a particularly fast, effective method of removing scale, rust, paint, and minor surface flaws from metal objects.
Depending on the shot blast equipment and the type of shot used, various surface finishes or textures can also be applied to a work piece for decorative purposes, or to prep the surface for paint.
There are some parts no suitable for blast cleaning, such as thin body panels which can get distorted.
Shot blasting is an essential part of good preparation, as it removes all contamination as rust and corrosion and leaves a good clean surface for applying the primary first coats of powder coat or wet paint’s.
