Has anyone ever applied new eternabond over old eternabond?

I would use a heat gun and remove the old tape first,

I have lapped it on a edge I failed to roll hard when first applied. Other than about six inches I missed with the roller, I have never had to.
Good stuff for sealing a lot of things. My last use was sealing the cap on a receptacle on my power pole for my RV shed

See #2 about the heat gun and removal. This technique leaves some residue of the old tape. If no dirty spots are showing where the old tape was removed, you now have a good surface for applying new tape. Otherwise, the dirty spots need removal with alcohol. Don’t use soap of any kind; it leaves a waxy film that new tape will not stick to.

It was new over old, but I used overlapping strips (lapstrake style) to cover a huge hole in a metal roof caused by a plunging tree limb. It was still holding fine 15 years later.

Eternabond is "considered a permanent Repair by EPDM roof MFRs" according to something I read, but saw one youtube video of (maybe another brand? Maybe TV ad brand?) that had long splits in it? That said, clean/ dry, I would have no fears about adding another layer, or overlapping? Good Luck.

How about using Goo Gone? Will that also leave a residue that will cause problems later? Or will dry Goo Gone be an issue with new tape?
