    Customers are mixed about the seal. Some mention it works, while others say it didn't eliminate the leak. Some say it forms a loose seal that was immediately defeated by light. Overall, opinions are mixed and the product is not intended for repairing leaking hoses.

    Great for Fiberglass Antennas

    Great for Fiberglass Antennas
    Well I am a Ham Radio operator and I had some antennas made of fiberglass and wire. Problem with fiberglass in FLORIDA is the sun bakes it and causes it to splinter and gets into your hands and clothes. I cleaned the fiberglass up and got most of the loose stuff off and then used black spray paint on them. After that dried I used Flex Seal clear and sprayed the 4 antennas with a coat and let it dry. I then put on a second coat and let that dry. I now have a waterproof antenna that the sun will not bother and the coax connections are 100% waterproof.Great product and covers a pretty good area. If you are a Ham Radio operator and have problems with rain changing you SWR on a antenna the this is what you need.Davede W4DRA

    1.0 out of 5 stars Snake Oil
    Reviewed in the United States on December 24, 2023
    I bought a can of this snake oil in 2017. I've tried several repairs and have yet to succeed. I followed the instructions and applied several even coats to a clean surface, but it just didn't seal.
