OK, finally had an opportunity to try some of his magic tape. I had a landscaping light that was out, and I thought it was just the bulb. Opened it up, and it was a third full of dirt and moisture. Ants had tunneled up into the enclosure and made a home there. I had a new replacement fixture, so I cut the wires, spliced and soldered in the new one, and got a roll of the tape.

What a pain in the ass! The stuff has a separating layer which is a thin piece of white plastic that must be peeled off before using. That was the first challenge. Then it has to be stretched to 2/3rds of its width and overlapped by 1/2 while wrapping. Easier said than done when working with small gauge wires.

In the end I got the splices wrapped, and now it will be interesting how well it holds up to outdoor, exposed use. Interesting stuff. Thanks, Greg.
