I've used GE Silicone II as a bonding agent & it does work well. Trust me, you won't go wrong using it for this application. But if you weren't happy with the results, it can be removed with no harm to the finish of the box. (run some fishing line behind the badge to break the bond) Given my results in the past, I'm sure you'll be pleased. Put a light film on that badge, let it set & guarantee it won't come off unless you take it off.
You can buy it in a small tube, white or clear. No need to buy the larger size for a caulking gun. My $.02.
