Professional In-House Protection at Champlain Chevrolet

At Champlain Chevrolet, we know firsthand what Vermont roads can do to a vehicle. Road salt, moisture, snow, ice, gravel, and fluctuating temperatures create the perfect environment for rust and corrosion to develop. That’s why we’re proud to offer Extreme Undercoating, a professional in-house protection service designed to help safeguard your vehicle from the harsh conditions of New England driving.

Whether you drive a Chevrolet, Ford, Toyota, Honda, Subaru, or any other make and model, Extreme Undercoating is available to help protect your investment. Applied by our trained technicians right here at Champlain Chevrolet, this advanced undercoating system helps shield your vehicle’s underbody from road salt, water, dirt, and debris that can lead to costly damage over time.

Why Choose Extreme Undercoating?

Extreme Undercoating helps:

  • Protect against rust and corrosion
  • Defend your vehicle from harsh Vermont winters
  • Shield exposed metal surfaces from road salt and moisture
  • Help maintain your vehicle’s appearance and resale value
  • Extend the life of underbody components
  • Reduce the risk of costly rust-related repairs
  • Provide year-round protection from the elements

Our Advanced Two-Part Protection System

What makes Extreme Undercoating different is its comprehensive two-part application process that protects both the hidden and exposed areas of your vehicle.

Internal Cavity Protection

The first part of the process is a specialized cavity protection treatment applied inside critical areas of the vehicle, including the fenders, rocker panels, hood, doors, and other enclosed sections where moisture can collect. This product penetrates hard-to-reach areas and helps protect from the inside out. Because it remains inside these protected cavities, it is designed to provide long-lasting protection and is not exposed to the elements.

Exterior Underbody Protection

The second part of the process is the durable black undercoating that is visible underneath the vehicle. This protective layer is applied to exposed components including the frame, suspension parts, underbody supports, and truck bed structure. It helps defend against road salt, moisture, dirt, gravel, and debris encountered during everyday driving.

The lifespan of the exterior undercoating can vary depending on driving habits, road conditions, winter maintenance, and overall vehicle usage. Under typical Vermont driving conditions, we generally see the exterior coating provide effective protection for approximately four years before a touch-up or reapplication may be recommended.

Together, these two layers create comprehensive protection against rust and corrosion, helping preserve your vehicle’s condition and value for years to come.
