Our Process
NEPA Undercoating Rust Prevention Process
To provide protection for your vehicle we use a specially formulated petroleum based oil that is Eco-friendly and completely non-toxic. It is designed to creep over time and migrate into hard to see and reach areas such as body seams and attachment points.

The process is as follows:
- The vehicle is raised on our lift and inspected.
- Rocker panel plugs are removed allowing access to the inner rocker panel to be treated.
- The inside of the doors are fogged.
- Tailgate is opened and fogged.
- Hood is opened allowing the hood, and fenders to be fogged.
- Entire undercarriage is then sprayed by 2 technicians.
- Both technicians then inspect the application looking for places missed and wiping any excess material
- Customer is encouraged to inspect and ask questions.
- Vehicle is lowered.
Upon finishing our rust prevention procedure the customer can immediately use the vehicle. There is no need to wait for the product to dry.
