LIQUI MOLY 3039 is a protective coating from LIQUI MOLY developed for cavities and corrosion-prone metal parts. 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 cavities and corrosion-prone metal parts 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.

• Long-lasting protection that helps avoid costly repairs
• Builds a durable protective film on cavities and corrosion-prone metal parts
• Seals out moisture, road salt and corrosive grime

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.
