I understand with the older cars, they can't even find the gas cap. But with the newer cars there's no reason to pump it yourself. I've had gas drip down the side of my old Indy Pace Car and never had a problem with it staining or damaging the paint. It's a matter of keeping your car properly protected. I find it funny that people won't put the effort into maintaining their car's finish but they'll pump their own gas.
