I bought a floor jack today that was near a car lot that specializes in sell barn finds/used hot rods.He has a 55 Chevy wagon two door windowed car.It has rust threw on the front door pillar by the bottom of the windshield/cowl.My question solely out of curiously is that common on those cars??. Kind like some other older cars there is a common area that normally rusts out.Is there replacement patch parts for areas like that??.
