your bodyman knows what he says when he told you to keep them off the exterior sheetmetal. Blasting warps. Period. Even if somebody tells me they can blast without warping I say "no thanks" I wont risk warping nice original sheetmetal. Id rather spend some time sanding than trying to fix wavy panels afterwards and having to use bondo (noooo!!!noo! nooooo!!!!).



Domingo. if i can blast a coke can and not warp it i can blast your sheetmetal. there are different medias for different jobs! I do not blast equipment and structural steel i blast vehicles. Might want to research some more options before saying all blasting warps.



Is that an empty can? If so, I would be impressed.




Yes it's an empty can... question is was the can empty the whole time it was being blasted.... Not just while you touch around the pull tab...... I've seen those cans at blast company displays, I've also seen them warp panels... Not as bad as the typical sand blaster but stuff your see trying to block a straight panel that takes extra priming... That just happens to be linear in the same direction as the blasting was preformed...



I am not located in the US, not I have seen all the blasting equipment available, but I can tell you I have tried a few different guns at very low pressure and have blasted with sand, silica, soda, and plastic pellets....and everytime I did notice some warping. The worse is when you blast a panel thats FLAT. That can is cylindrical...if it was a 24 gauge STEEL can I could probably blast it at low pressure and not cause any warping. I really doubt an empty ALUMINUM can could be blasted without warping!!!!

For instance....I would NEVER NEVER EVER blast a 68-69 Charger trunk lid no matter what equipment you use. It WILL warp. Period. and there is no way on fixing one of those once its warped....the underbrace has no openings so there is no way of fixing the skin once it warps...once it warps either its junk or you have to do some BONDO MAGIC .
