Krown St. Louis · Mobile & In-Shop Service

Fleet & Municipal
Rust Protection

Road salt and de-icing chemicals attack steel and electrical components on every vehicle in your fleet — squad cars, plow trucks, transit buses, dump trucks. Krown applies rust inhibitor to 200+ points on each vehicle, on-site with our mobile rig or in-shop, once a year.

Municipal Fleets

Every Ton of Salt Has a Bill Attached

Public works, police, transit, and fire/rescue fleets represent serious taxpayer investment — and road salt damage is one of the largest unbudgeted costs in fleet maintenance. Because this kind of damage is treated as ordinary wear and tear, it typically isn't covered by insurance — the full cost lands on your maintenance budget every year. We schedule around your fleet's calendar, including nights, weekends, or slow season, so vehicles stay in service.

Corrosion Doesn't Wait for a Trade-In

Trucking, logistics, courier, and construction fleets lose money to corrosion two ways: expensive electrical repairs — connectors, sensors, wiring harnesses — and early retirement of otherwise-serviceable equipment. Krown's non-conductive formula creates a protective barrier around electrical components and penetrates the seams and spot welds where rust starts first.
