LIQUI MOLY 1540 is a protective coating from LIQUI MOLY developed for bare and welded metal surfaces. It forms a durable film that seals the surface against moisture, road salt and corrosion before damage can take hold. A small amount of prevention here saves expensive bodywork repairs later.

Purpose and specifications

This product is designed to protect bare and welded metal surfaces against corrosion and environmental stress. Applied as an even coat, it bonds to the surface and builds a resilient barrier that withstands moisture, dirt and mechanical wear far longer than untreated metal.

• Seals out moisture, road salt and corrosive grime
• Long-lasting protection that helps avoid costly repairs
• Builds a durable protective film on bare and welded metal surfaces

When to use / change?

Apply it to clean, dry and rust-free surfaces — ideally before the winter season or immediately after repairs expose bare metal. Inspect the coating yearly and touch up worn spots. Stored sealed, the shelf life is approximately 5 years.
