Doug, I hate to contradict you, But when I was working on the Essex, the boss sent the fenders out for S.B.ing and the came back twisted like kandy kanes or barber poles. These were 1920 Essex, not model A, definitley a rare bird. I can't say what the media or pressures were, but they were very distorted.

If you are concerned, try an experiment before working on your car: Get a nice flat thin piece of sheet metal, and blast away, with the highest pressure you can generate. See how what sort of damage you are capable of doing.
