It really all depends on who is doing it,but believe me,you CAN tear the crap out of the sheet metal with sand(as well as other media.)It is not just the abrasion of the sand,it has alot to do with the heat generated on the steel.ALSO,alot to do with the CFM of the air supply of the compressor and size of the equipment.My family did it for several years.You ought to see the king of damage you can do with a 675 CFM compressor and a 2" feedline with a 5/8"or a 3/4" nozzle !!!! I have sent out sheet metal that looks in good condition when it comes back,but after you start body working the metal,you can REALLY see and feel the "wave" in the surface that was left behind by a "harsh" sandblast job.I am not saying sand cannot be used,but the safer medias made for body panel cleaning are MORE fool proof.LESS likely to tear up anything under all kinds of different air pressures,CFM,distance from panels.It really is mostly to do with the person doing it,and on RARE parts being blasted,it AINT worth taking a chance on !!!!
