OK, to the right is what it should look like now.
Apply a generous coat of epoxy to the connections for strength and weatherproofing (see the left picture at the bottom).
Not all epoxies are created equal, be certain to test a cured lump in a microwave oven before using it on the antenna. Place your epoxy sample next to a cup of water in the microwave, and cook for 1 minute. If the epoxy is hot, try another brand. Just warm is OK.
The second picture below shows a final coat of white latex paint
covering the epoxy seal and the copper dipole.
