Why Undercoating Matters

Salt air, water, dirt, and grime can work their way into the smallest crevices of your vehicle’s undercarriage, leading to rust and costly repairs over time. Undercoating creates a long-lasting shield that:

  • Prevents rust and corrosion from forming.

  • Protects against salty ocean air and harsh chemicals.

  • Extends your vehicle’s lifespan and resale value.

  • Reduces road noise for a quieter ride.

Here’s how our professional process works:

  • Vehicle Lift Inspection

    Your car or truck is raised on a two-post or four-post lift, giving our technicians full access to the underbody.

  • Rust and debris removal (If needed)

     If needed, your vehicle will have any heavy rust sanded off and removed, along with any debris that would block or interfere with the application of the undercoating.

  • High-Pressure Undercoating Application

    Our high pressure spray guns deliver an even, consistent layer of protective coating to every exposed surface — including frame rails, wheel wells, and suspension components. Our specialized attachments allow us to spray the interior rails and any access panels to help prevent rusting from the interior portion of panels or frames.

  • Complete Coverage Guarantee

    Because we work from underneath the lifted vehicle, no spots are missed, and the protective barrier lasts longer.
