Bilt Hamber Epoxy Mastic Anti-Corrosion Coating 1L

Epoxy Mastic is a powerful anti-corrosion coating from Bilt Hamber, developed for chassis, underbody and other structural parts that need heavy-duty protection. The epoxy formula has high covering power and forms a tough barrier resistant to chemicals and abrasion. The coating bonds to bare metal, primed surfaces and even existing paint, making it suitable for both classic car restorations and modern vehicle maintenance. Professional restorers and bodywork enthusiasts choose this product for maximum durability and protection against rust and corrosion. In restoration projects, the coating is often used as the first protective layer, before finishing with a topcoat or underbody wax. Work in a well-ventilated area and wear gloves during application.

What's inside

1x Bilt Hamber Epoxy Mastic Anti-Corrosion Coating in a 1 liter pack, for chassis and underbody.

Why this product

• High covering power in the epoxy formula gives maximum protection in a single layer, even on large surfaces.

• Resistant to chemicals, weather and abrasion, so the protective layer holds up long-term under heavy loads.

• Bonds to bare metal, primed surfaces and even existing paint, making the coating versatile to use.

• Ideal for chassis, underbody and structural parts that need heavy, long-lasting protection against rust and corrosion.

How to use

1. Clean the surface mechanically, removing loose rust particles, grease and dirt. (This also works to prepare lightly rusted steel for a good bond.)

2. Mix the epoxy mastic according to the instructions on the packaging. (Work systematically to keep an even layer thickness across the whole surface.)

3. Apply the coating evenly with a brush or spray onto the desired surface. (This builds a solid barrier that protects chassis, underbody and structural parts.)

4. Let the coating cure fully before the part is loaded. (Curing time depends on temperature and layer thickness, so check the coating before continuing.)

Treat rust first with Deox-C, degrease thoroughly and mask adjacent parts for a clean result.
