My end result: I'm saying "Hello & welcome back, E6000!"
I lined a clippy yesterday and tried to peel it today. Peeled right off (ribbon to metal). So, I'm back to using E6000 for that ribbon-to-metal part.
On the good side,
~ Works good (of course) for ribbon to ribbon.
~ I LOVE it for lining the 30mm snap clips.
~ Padded applique to ribbon
Conclusion: E6000 is back: as my BFF.
