This is a genuine Volvo Penta OEM corrosion shield spray designed for marine equipment. It penetrates corrosion cells, displaces moisture, and leaves a thin protective film that helps repel salt spray and water. Suitable for use on exposed metal components, electrical connections, linkages, fasteners, and other hardware in harsh marine environments. Sold as an aerosol can.
Specifications
- System: Corrosion Protection / Preventive Maintenance
- Type: Aerosol anti-rust / corrosion inhibitor spray
- Packaging: Aerosol can (approx. 8–12 oz — confirm current packaging at time of order)
- Function: Moisture displacement, corrosion inhibition, light lubrication, protective film barrier
Compatible Applications
This is a maintenance and protection product, not an engine-specific hard part. It is suitable for use across all Volvo Penta marine engine families and drive systems, as well as any marine equipment exposed to salt spray, moisture, or corrosive environments:
- Exposed electrical connectors and terminals
- Linkages, cables, and pivot points
- Fasteners, bolts, and exposed hardware
- Battery terminals and ground connections
- Bilge hardware and through-hull fittings
- Any metal surface requiring corrosion protection in a marine environment
Alternate & Cross-Reference Part Numbers
- 21234027 — Volvo Penta OEM (this part, active number)
- 362002 — Superseded Volvo Penta reference
When to Use
Apply this corrosion shield spray when:
- Performing seasonal layup or spring recommissioning service
- Servicing electrical connections or components exposed to salt spray
- Treating exposed metal hardware after saltwater exposure
- Addressing early-stage surface corrosion on accessible components
- Adding corrosion protection during routine engine or drive service
Application Notes
- Apply to clean, dry surfaces for best adhesion and protection
- Particularly effective around electrical equipment, exposed hardware, and salt-spray-prone areas
- Acts as both a corrosion inhibitor and a moisture-displacing lubricant
- Follow the product label directions for safe application, coverage, and ventilation requirements
- Not a substitute for structural corrosion repair — best used as a preventive treatment
Service Interval
Apply as part of seasonal layup and recommissioning service, or any time electrical or metal components are serviced or exposed to increased salt-spray conditions. Reapply as needed based on operating environment and visual inspection of protected surfaces.
Technical FAQ
Is this safe to use on electrical connections?
Yes — this product is specifically recommended for marine electrical components and connectors. It displaces moisture and leaves a protective film that helps prevent corrosion at connection points.
Can it be used on all Volvo Penta engine families?
Yes. This is a maintenance product, not an engine-specific part. It is suitable for use across all Volvo Penta gasoline and diesel marine engines and drive systems, as well as any other marine equipment requiring corrosion protection.
Is 362002 the same product?
Yes — 362002 is the superseded part number. 21234027 is the current active Volvo Penta part number for this product.
How is this different from a standard WD-40 or penetrant spray?
This is a genuine Volvo Penta OEM formulation designed specifically for marine environments. It is engineered to meet Volvo Penta’s corrosion protection standards for their equipment and is the product specified in Volvo Penta service and maintenance documentation.
Parts Desk Insights
Salt and moisture are the two biggest enemies of marine electrical systems and exposed hardware, and the damage usually happens gradually — long before a connector fails or a fastener seizes completely. This spray is one of the easiest and most cost-effective things you can add to a seasonal service. We see a lot of electrical gremlins and seized hardware on boats that skipped corrosion protection during layup. If you’re already doing engine or drive service, it’s worth treating the electrical connections and exposed hardware at the same time. A few minutes of prevention saves a lot of diagnostic time later.
