Lakefront air, the 427 and the 401: how location shapes wear
Streets close to Lake Ontario can be damp and windy, and moist air tends to be hard on steel hardware. Cable ends, brackets and the bottom edge of the door are the places we would expect rust to show first. Further inland, the busy corridors around Highway 427 and Highway 401 mean plenty of road salt in winter, and that salt travels home on tires and splashes onto the lower panel.
Many older Etobicoke lots also have a short driveway, so a car parked close to the door nudges the track or bumps the bottom corner more often than owners realize.
