Frequently Asked Questions About Underbody Rust Protection

Frequently Asked Questions

What is the best way to apply Underbody Rust Protection for maximum effectiveness?

For optimal results, apply the product in a clean, dry environment. Ensure the surface is free from dirt, oil, and wax. Follow the recommended application method and wait the recommended amount of time before washing or exposing the vehicle to moisture. This will allow the product to fully bond and protect the underbody.

Will Underbody Rust Protection void my vehicle’s warranty?

Most reputable manufacturers do not consider Underbody Rust Protection as a modification that would void a vehicle’s warranty.

If you’re unsure, consult with a dealership or the manufacturer’s customer service department for clarification.
