There is no reason to sand the vehical down that far unless your doing a full resto or the current paint has peeling / chipping problems
Been there, done that, had to strip the entire front end of MULTIPLE cars that a coworker didnt prep correctly and get them back into primmer.
Cars would come in with only certian areas chipping / peeling. For example a car w/ a new hood but a repaired bumper would only be chipping on the hood. Or the car with a replaced fender and repaired bumper that tail gated a salt truck for 60 miles only had chips on the fender (and a buffable bumper.
How WELL you prep (and how well the guy who last painted the vehical did so) have more impact on the quality then how much paint you strip off.
