*Sand blasting of thin sheet metal causes peening that may cause the metal to ding, warp, or pit. Be aware of this, especially if you are going to be doing a long, flat, unsupported body panel. The best way to avoid this on long spans is to spread out the blast from the gun so that not one area receives the brunt of the abrasive blast for a long period of time. It also gives it time to cool. | *Sand blasting of thin sheet metal causes peening that may cause the metal to ding, warp, or pit.

*Most media recycles very nicely, with the larger particles breaking down into smaller, sharper ones. Eventually, it will be broken down so far that it cannot diffuse into smaller particles, and the media will have to be replaced. | *Most media recycles very nicely, with the larger particles breaking down into smaller, sharper ones.
