it depends , the newer cars and trucks are bathed in a solution that leaves a coating on the metal that looks like zink and it keeps the metal from contact to the atmosfere even paint isnt totally watertight and some spots you cant reach with paint .
the blasting removes the coating dipping doesnt .
if you want the body to last a looooooooooong time and you dont have to weld anything on it you could coat it with zink (in the netherlands thats called skopperen it involves a special spraygun that melts zinkwire with a propaneflame and sprays the melted stuff ontoo the metal this zinkcoating will preent rusting for a long time to come but its poisonous when you need to weld it (gets you a headacke and makes you dizzy like youre stoned or drunk )
