Rustproofing & Undercoating Services in Madison, WI

Capital Auto Protection offers professional rustproofing and undercoating services for vehicles in Madison, WI and surrounding areas. Our advanced corrosion protection is specifically designed to target high-risk areas like folds, seams, spot welds, and recessed metal panels — where rust typically starts.

We use high-pressure applicators and take advantage of your vehicle’s existing factory drain holes to access and coat hard-to-reach interior surfaces — without drilling into your vehicle. This ensures maximum protection with zero structural compromise.

Our durable undercoating treatment is engineered to seal out moisture, salt, and road grime, helping to prevent corrosion before it begins. It penetrates deep into seams and crevices, forming a long-lasting barrier against rust, oxidation, and harmful pollutants. Whether you’re protecting a new vehicle or extending the life of an older one, our rust prevention solutions are a smart investment for Wisconsin drivers facing harsh winters and salted roads.
