Walnut shells are ideal for use in a sandblaster. The process of sandblasting involves the use of an abrasive material such as walnut shells, to strip off the uppermost layer of some object like a boat, a vehicle, or anything else which has multiple layers of protective coating. Walnut shell sandblasting abrasive does little to no harm whatsoever to the primer coat underneath, or to any other coating which has been applied to an object.
Before the discovery of walnut shell blast media, any object which needed rust or corrosion removed, had to be stripped right down to bare metal. This of course, was a more time-consuming and costly process, and it often did at least some damage to the metal underneath. Now with the usage of walnut shells for sandblasting, a much gentler process is possible, and only the top layer of any protective coating is affected.
