How do I protect my car from Michigan road salt?

Road salt is the defining threat to a Michigan vehicle, and it works on two fronts. On the painted surfaces, salt and brine combine with grime to dull the finish and, where the clear coat is chipped, to start corrosion. Underneath, salt collects in wheel wells, frame seams, and on brake and fuel lines, holding moisture against bare steel and driving the rust that shortens a vehicle's life.

Defending against it takes a layered approach. The first and most important habit is frequent washing through the salt season, every one to two weeks, and crucially including the underbody, which most drivers skip. Removing salt before it sits is what prevents the damage. The second layer is paint protection: a fresh wax or, better, a ceramic coating makes salt and grime rinse off far more easily and adds a barrier over the clear coat. The third layer is the underbody itself: an undercoating or rust-inhibitor treatment applied before winter creeps into the seams the wash cannot reach and stops corrosion on the metal that matters most.

Timing helps. Apply paint protection and underbody treatment in the fall before the first salt goes down, and keep up the winter wash cadence through March. Trucks, SUVs, and older vehicles carry the most exposed metal and benefit most from the underbody work. Car Hub in Macomb offers the ceramic coating, paint protection, and rust-prevention services that make up that defense.
