A lot of people put electrical tape on the ends and at Y’s of convoluted split tubing to keep the wires addressed. But even with high quality tape, heat tends to melt the adhesive, leaving a mess. So I have this tip that has been working for me.
I first tape the tubing. Then, I take Liquid Tape and paint over the electrical tape, all around the taped joint, especially where the tape seam is. A second coat doesn’t hurt. This stuff dries super quick, looks great, and keeps the tape intact.

They do make high temperature electrical tape. I don't know part numbers or brands offhand. Scotch #33 is NOT high temperature.
I have found that it sticks better if you stretch it at the end of the wrap and don't touch the adhesive with your oily fingers. I have tucked the end of the tape back under the last loop and then pulled it until it broke. Tightens and secures it at the same time.
And when the stretched tape gets hot, it will try to shrink back to it's original size leaving the "mess".
Scotch Super 33+ is rated for 220*F. It may not be considered high temperature but has about the best long term adhesion for outdoor use that is readily available to the consumer. Please share the link with the high-temp tape.
