In removing paint for auto body work, bead blasting is preferred over sand blasting, as sand blasting tends to create a greater surface profile than bead blasting. Bead blasting is often used in creating a uniform surface finish on machined parts.
Sand blasting is also known as abrasive blasting, which is a generic term for the process of smoothing, shaping and cleaning a hard surface by forcing solid particles across that surface at high speeds;
A variant of wet blasting is vapor blasting. In this process pressurized air is added to the water in the nozzle producing a high speed mist, called “vapor”. This process is even milder than wet blasting, allowing mating surfaces to be cleaned while retaining their ability to mate.
