Wash away winter salt
Rinsing road salt from accessible underbody areas can help limit prolonged exposure. Use care around sensitive electrical and mechanical components.
Inspect common trouble spots
Look at seams, brackets, pinch welds, subframes, brake and fuel line areas, and places where mud and moisture collect. Some problems are hidden until a closer inspection.
Remove loose rust appropriately
Flaking scale and loose debris may need to be removed before protective treatment. Avoid aggressive grinding near thin metal, wiring or lines.
Repair damaged components
Corroded brake lines, structural mounts and severely weakened metal need proper repairs. A coating cannot make them safe.
Choose the right protection
Undercoating can reduce future moisture and salt exposure when applied correctly. Product choice and preparation should match the vehicle condition.
Recheck after winter
Regular inspection helps identify missed areas or new damage before it spreads.
