Has anybody considered/tried putting something on their LPS danglers to prevent scratches?

Hello! I have this adorable lps dangler ive used as a phone charm and I LOVE HIM. But he has some scratches and im afraid it's going to get bad in the future :( Does anybody have any ideas on something I could put on it to protect it? Like for a lack of a better example mod podge? He's so adorable and he reminds me of being a child and I don't want it to be so banged up.
