Corrosion Block in this 4 oz pump spray supplies one 4 oz pump spray, identified by SKU 72602 and MPN 20002. A compact 4 oz pump spray for a small maintenance kit or controlled access to compatible fittings and electrical-component locations. Select the package by the work you plan to do and the way you want to dispense the product, while keeping the exact formula instructions with the maintenance supplies.
Corrosion Block is a corrosion-inhibiting fluid designed to penetrate affected areas, displace moisture and leave a protective film. Manufacturer literature describes spray, brush and wipe application for appropriate surfaces. That makes the delivery format an important purchase choice: a pump, aerosol and refill container offer different ways to supply the same maintenance task without establishing that every surface or electrical assembly should be coated.
The 4 oz pump spray is the exact purchase format for code 20002. Pump dispensing is a format choice, not proof of universal material compatibility or electrical approval. Aim and apply according to the exact label and equipment requirements. No fixed surface coverage or universal application count is assigned to this package.
Manufacturer guidance identifies metal protection and electrical-component applications. Confirm the exact equipment, materials and application location; isolate electrical power before servicing and follow the equipment procedure. Inspect the treated component as part of regular maintenance and plan further care from its condition and exposure. Compare like-for-like formula and package choices before judging the size of the supply.

What Customers Say
Excellent protection for marine electronics
Applied this Corrosion Block spray to battery terminals and electrical connectors on my boat after a season of saltwater exposure. It penetrated well, stopped existing corrosion, and left a clean protective film. Shipping was fast and the 4oz pump bottle is easy to use in tight spaces. Great value for reliable performance.
Stops corrosion on contact and protects well
Used the Corrosion Block liquid pump spray on switches, fuse panels, and connectors around the engine. It kills corrosion quickly and leaves a clear hydrophobic film without any greasy residue. Order arrived quickly with secure packaging. Non-toxic and non-flammable formula makes it safe for frequent use. Solid value for the performance.
Effective but wish the bottle was larger
This Corrosion Block spray works great on battery terminals and electrical connections. It penetrates deeply and prevents new corrosion effectively. Fast shipping and correct product arrived as described. Application is straightforward with the pump sprayer. Only minor drawback is the 4oz size goes quickly with regular boat maintenance, but overall good value and performance.
Reliable for boat and trailer electronics

Product shipped quickly and arrived undamaged. Easy pump application and non-hazardous formula make it a go-to for maintenance. Excellent performance and value.
