Looks better than any time I've tried.
It made a huge difference in my Tele that came unshielded. I use compression and gain, so a badly shielded guitar is a problem. Noticeable hum reduction when I added the shielding tape. If it’s already got shielding paint, probably much less effect.And IME doesn't really make a lot of difference when using single coil pickups.
I don't think I've ever actually shielded a guitar for myself. I've only ever done it for friends while putting in pickups for them (at their request).And IME doesn't really make a lot of difference when using single coil pickups.
I've done it on a couple of Strats, and found it was not worth the effort.It made a huge difference in my Tele that came unshielded.

^This.None of my three main Stratocasters ( SSS/HSS) have cavity shielding just the Scratch-plate and are very quiet. If the grounding in the location is working as it should there's no need for over-shielding.
Does gold leaf offer shielding? If so, much easier to work with, have some experience with both copper and gold.
