Chassis Shield DIY Rustproofing Spray

Endrust Chassis Shield – Clear Rust & Corrosion Preventative

Endrust Chassis Shield is a clear, spray-on rust and corrosion preventative designed for vehicle owners who want reliable underbody protection without the need for specialised equipment. Built on over 40 years of Australian rustproofing expertise, it delivers a clean, dry-to-touch finish that actively repels salt, mud and water — helping keep surfaces cleaner for longer.

Ideal for DIY application, Chassis Shield forms a durable protective barrier that lasts 12 months or longer*, depending on use conditions. Whether you’re towing, touring or storing equipment, it’s an easy and effective way to safeguard exposed metal.

Application

1. Thoroughly clean and degrease the surface — remove dirt, grease and tyre shine.

2. Ensure the surface is completely dry.

3. Spray an even coat over exposed chassis and metal components.

4. Allow 3 hours before sealed road use.

5. Allow 1–2 days curing before beach driving, saltwater immersion or off-road use.

6. Perform a touch test before harsh exposure.

7. Avoid application to exhausts or engines.

Duration of Protection

Protection typically lasts 12 months or longer on vehicles driven mainly on sealed roads. After frequent beach driving, saltwater exposure or heavy off-road use, we recommend reapplication as needed to maintain full protection.
