Flaking Paint

[Killerf6]

Hey all,
I have a ZPA spit (the one with the black and white underside). I have noticed recently that some of the white paint is flaking off.

What I want to know is has anyone else had simular issues with any of their XD? Any ideas why this is happening to just this one plane? Is this a known issue with the ZPA spit?

I checked all my planes that are displayed and the ZPA spit was the only one I saw with the paint flaking. The room where most of my planes are displayed has no direct sun light, there are no temperature extremes, and the area where the paint flaked wasn't in contact with any other surface. Any info would be appreciated.
