Query: One of the best sealers for electronic applications

I'm a ham radio operator and have used Coax Seal for about 3 years. Coax Seal is the best near-permanent sealant for outside antenna connections and splices, especially for buried splices. Installing Coax Seal is fast and easy with the finished product being a water and weatherproof seal that will last for years to come. I would recommend Coax Seal to anyone who requires a weather proof seal for any kind of electronic or electrical equipment.
