## Description

H&H CB12 Corrosion Block, 12-Ounce Aerosol Can

Review: If you are concerned about preventing corrosion then this is a great product. We have a place on the water and our electronics eventually all suffer and corrode. This applies a coating of protection which I have now used on the plugs, cables, HDMI's etc. I have also applied it to my wrought iron furniture where it is chipped and it added a layer of coating. I read about this product online but couldn't find it locally so I was very happy to find it on desertcart.
Review: Product is easy to use and excellent for correcting intermittent electrical connections on low voltage circuits. Also works amazingly well on keyed door locks. Lasts a long time (years) with proper re-application. Targets the invisible corrosion often occuring between copper circuit boards and tin connectors.
