Another issue is now you have clean metal that wants to flash rust unless dipped in a rust inhibitor such as a phosphoric acid solution. Lots of that metal is in places that will never see paint. Crazy as it may sound a dip in some sort of primer is a good answer, but who has a vat of primer?
That would be my concern also, no one here in my metro area has a vat that can turn a cab upside down. Like the factory does today.
