If you have problems with disconnects in connections exposed to the environment, I recommend this product. I repeat that a very small amount of this product makes a big difference. Don't pick it up because it's sticky and difficult to remove without lots of dish soap and a scrubbing brush. I have used it in connectors that are exposed to the elements under the hood of a car and I use a wooden toothpick to take a small amount of this product to rub the inside of the socket and then assemble the connectors. It retains water and the carbon provides a better electrical connection surface. I recommend this product. Do not be careless with this product and only wear it when the plus and minus poles are close together. The chance of a short circuit is high if you are not careful in the application and placement of the product.
