This is the standard 12 oz. aerosol spray can of Corrosion Block, but there is a slight defect to the can and cap, so it sells at a heavily discounted price.
Nature of defect: a small amount of product was released and it stained inside of the plastic cap and the area around the nozzle of the can, as seen in the picture. It is a cosmetic defect only, with no change to the product. Each can will be test sprayed prior to shipping to ensure it works properly.
This item is non-returnable.
