CA glue is super glue. Used it a few times myself. When installing the rare and hard to find trim tape on Cat gas tanks, KKK let me on a method that works.
First remove the adhesive backing with "Goo Gone." On a foil sticker, this product won't cause damage to the graphics, but I'd test it just to be sure.
Once adhesive was gone from your decal, (soaked through) I'd carefully peel it with a straight razor blade. I'd remove all the remaining adhesive from it, clean it, clean the metal where it goes.
Then I'd tape off the area where the sticker is going to be placed. In that area, I'd apply a thin layer of contact cement. I wouldn't use the spray stuff, since it's too hard to control. I'd also to a thin coat on the sticker itself. Let the whole thing cure for 15 minutes and press it on. Do it right, because it's a one shot deal.
That's how I'd do it, and that's how I've done the trim tape on the Cat fenders.
