[Q] Z3+ Exterior Black Paint

Hi,

I have searched nearly everywhere, even on google and i cant seem to find an answer. Would appreciate if someone (with the Z3+ black color device) can shed some light on this. On the Z3 black version, the metal frame is painted in space grey. However, after some time of use the paint comes off if scratched on other hard surfaces and reveals the aluminium color.

So my question is, does the Z3+ black version have the same issue? I know for a matter of fact Sony used some other materials to make the frame shinier, does the paint come off and reveals the aluminium?

thanks in advance.
