Help: Paint degradation on Luke BFR

Im having troubles with the paint on the back of my Luke II BFR.
Suddenly the paint is cracking and bubbling up. It looks very bad. Has anyone experience like this?
It has been stored in room temperature – No extremes.
I think the paint is ruined for good but only on the back.
It would be nice to avoid the same on the front, so any advise will be appreciated 🙂
It hard to capture in pictures, but I have tried 🤘

Regards and thx – Hans
