Unlike that of Astray Red Frame, the armors are for the whole model it seems.
More details will be released soon.
Some shops actually put this special armor set as part of the special prizes for PG 00 Gundam, even though the official information from Bandai (the PDF file on the official site) says that the armors can only be obtained by purchasing them using a ticket included with the special prize set for the initial batch of release.
With regard to that, I'll be following that statement, and any other methods to obtain the armors are only true to the dealer or seller of that country or area.
But there's no mistake that the other special prize to be included is the display base.
November release, 26,250 Yen (inclusive of tax).
