What We Do
Professional Rust Protection Services
01
Woolwax Undercoating
Woolwax Undercoating Video
Lanolin-Based Full Undercarriage Non-Hardening Self-Healing
A professional lanolin-based formula applied to your entire undercarriage — frame rails, floor pans, suspension parts, and exposed metal. Creeps into seams, self-heals minor scratches, and protects against road salt year-round. Rotating parts, engine, transmission, and brakes are masked and not coated.

Inner Cavity Wax

Cavity Injection Doors & Pillars Hidden Seams Wheel Wells
Stop rust where it starts — inside door cavities, pillars, rocker panels, and structural seams. Injected directly into enclosed metal spaces that standard undercoating can’t reach. Best combined with Woolwax for total corrosion protection.

03
Salt Neutralizer Wash
Add-On Service Pre-Coating Prep Full Frame Flush
Road salt and liquid brine penetrate into seams and cavities a standard car wash can’t reach. We flush the full undercarriage with a salt neutralizer before any undercoating service to maximize adhesion and protection. Available as a full frame flush or exterior-only rinse.

04
Rust Removal — Needle Scaler
By Estimate Only Pneumatic Scaler $90 / hr
Mechanical removal of loose and scaled rust using a pneumatic needle scaler before undercoating is applied. Extent of rust determines time and cost — we assess and estimate in person before beginning. Recommended before any undercoating on vehicles with existing corrosion.

05
Rust Converting Primer
By Estimate Only Stops Oxidation $275–$475+
Chemical primer applied directly to rust-affected surfaces to convert and stop active oxidation, bonding with the bare metal before undercoating is applied. Best used in combination with needle scaler rust removal for heavily corroded vehicles. In-shop estimate required.

Add-On Service
Salt Neutralizer Wash
Road salt and liquid brine are a silent disaster for your undercarriage. A standard car wash doesn’t reach the tight cavities and crevices where salt accumulates and accelerates corrosion. We offer a dedicated salt flush before your undercoating service.
