And yes we use heat shrink with the sealing adhesive inside; the corrosion just travels right under it along the surface of the metal. I actually found electrical tape seals better, it just doesn't look near as good, so we still use heat shrink, and coat over the heat shrink with the vaseline (or grease).</div><div><br><div>
