Surface finish looks a bit bright for paint adhesion.
This is my concern as well. I fail to see how paint can fail in this manner. I am a specialist in adhesive bond failure forensics and such a failure in an adhesive bond should ring alarm bells even if it is not a direct cause of the failure. I ask again if any part of that structure is adhesively bonded? If it was bonded then adhesion failures such as that are an extreme warning of exceptionally poor bond strength. If not, then questions must be asked about how paint can just peel off like that. Such a surface finish provides absolutely no environmental protection whatsoever. Adhesion failures in adhesive bonds or paint are indicative of exceptionally poor preparation processes. And before anyone suggests it, a crash event can never change the failure mode in adhesive bonds or paints. The interface is already exceptionally weak and impact can not cause such a change in failure mode.
