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

I've used this anywhere I'm concerned with corrosion from moisture or high humidity. I have used it on boats, airplanes, cars, and fire engines. Besides nuts and bolts, there is no problem soaking down electrical connections either. A little pricey but a can lasts a long time. The area of the application on the item you have sprayed seems to be protected for several years in my experience.

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 Amazon.

Great product for using appropriately.

It really works. I have tried a lot of anti corrosion and break free products, this one delivers. I don’t give 5 star reviews, a 3 stars from me means it works as advertised. This neutralized the rust on aluminum, steel and pot metal. It also brought back luster to binge black paint and black plastic which I discovered by accident with overspray. I do not yet know how long that will last as the items treated have yet to be out in the elements

Thought it was going to stop the battery from working after spraying it on my battery connection but after a mile or so the battery started to work but l haven't ride my bike in the rain not sure weather it has made a difference yet
