− | + | Sandblasting sheet metal is controversial, and often ill-advised. | |
− | * Prolonged sand blasting of thin sheet metal causes frictional heat (''frictional heat, or peening?'') that may cause the metal to ding, warp, or pit. Be aware of this if you especially 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. | + | *Prolonged sand blasting of thin sheet metal causes frictional heat (''frictional heat, or peening?'') that may cause the metal to ding, warp, or pit.
