Personally it hard to imagine anyone sandblasting the intire body. I would save sandblasting for only the really rusted areas that need it.
Don't be lazy, put the time and labor into sanding just enough to get primer to bond.
When sandblasting, don't try to do it all at once or too fast or too high a pressure.
litely go over an area letting the metal stay
cool so it doesn't warp,then come back for ever how many passes it takes to do the task.
It is a crime to ruin good sheetmetal
by over heating it by warping it,sanding too much at too high a pressure. There are places around that dip strip auto bodies down to the bare metal!
