Rusfre Undercoating

Rusfre Undercoating: Professional-Grade Rust Prevention from the Ground Up

When it comes to protecting a vehicle's undercarriage from the relentless assault of moisture, road salt, and road debris, few names carry the credibility of Rusfre. Their undercoating products have earned a reputation among professional body shops and dedicated DIYers alike for delivering factory-level corrosion protection through a chemically engineered, rubberized formula that genuinely performs over the long haul.

What Sets Rusfre Undercoating Apart

At the core of Rusfre's undercoating line is a heavy-bodied rubber and asphalt formulation that goes beyond simple paint-on coverage. Rusfre's formula features a heavy-bodied rubber and asphalt composition, enhanced with cellulose fibers for durability. Those cellulose fibers are a key differentiator: the undercoating is a heavy-bodied rubber and asphalt coating for rustproofing, sound deadening, hiding repairs, and sealing — and the cellulose fibers add strength and prevent chipping.

Unlike rigid coatings that crack and flake under thermal cycling and road vibration, Rusfre's flexible, soft undercoating covers effectively, is resistant to chipping, cracking, and peeling, sprays evenly, and stays soft to the touch — it won't dry out. This flexibility means the coating moves with the vehicle's metal panels rather than working against them, maintaining an unbroken protective barrier season after season.

Multi-Benefit Protection: More Than Just Rust Prevention

Rusfre undercoating is engineered to deliver several layers of value in a single application. It is specifically designed to prevent rust and corrosion on metal surfaces, efficiently reduces noise with sound-deadening capabilities, provides excellent adhesion to various surfaces including metals and plastics, and is resilient against chipping, cracking, and peeling.

The chemical formula reduces noise levels comprehensively by deadening sound in quarter panels, fenders, undercarriages, and wheel wells. For anyone restoring a classic car or refreshing a daily driver, that acoustic benefit alone makes Rusfre a compelling choice. This rust-preventive material does not contain asbestos , and the undercoating is proudly made in the USA.

Application: Designed for the Rusfre System

Rusfre undercoating is formulated to work in harmony with dedicated application equipment. Made especially for use with Rusfre BBB Guns, the rubberized, chemically formulated rust preventive contains bound fibers for bonding to prevent chipping. The flagship product — the Rusfre 1020F-1 — is available in 1-gallon jugs, giving users enough material to cover an entire vehicle's underside in a single session. This rubberized chemical formula prevents rust effectively and provides excellent adhesion to painted as well as unpainted surfaces, and is perfect for protecting newly repaired auto body areas from dust penetration.

Whether you're maintaining an entire fleet or completing a frame-off restoration, Rusfre products and accessories are affordable and effective for rustproofing and undercoating, and the brand offers an easy-to-operate rust proofing and undercoating system with accessories for every application.
