[Unanswered]  Zero G sticker care

I have been collecting a bunch of Zero G beys lately, cause the format is cool and also they're so pretty, and the second part is mostly what I'm here for 

My other Zero G beys have a very hard time holding onto stickers in some cases, and a decent amount of them have come off, and I just want to pick the brains of any vets here. Any ways to prevent stickers from getting too damage/falling off Zero G Beys? I've seen advice for clear coat to protect them maybe? Or is it better to just leave stickers off or get duplicates to play with vs display? 

I look forward to advice : D
