"I bought some magic wrap rubber tape"
Is that the stuff that they use for plumbing repairs? Never thought of using that (but grease could still be a problem tho).
I should've opened the link before I asked - sorry.
I've used that stuff for plumbing & other stuff (including the Tone hitch install). It does work great - just don't let it touch itself until you want it to. It works best if it's stretched but that won't help for your project.
