Teflon tape would I imagine be way better than electrical tape in terms of not leaving any goo, better heat resistance, and better "adjustability" since its so thin. The down side would be many more wraps and more patience necessary because its so thin. No free lunch.Swampwalker,

An alternative might be 3M 70 self fusing silicone tape. It only sticks to itself and there is not any residue, none.....
