I got the AK INTERACTIVE TRUE METAL GOLD today. I applied it to my Super 7 Metropolis Maria, as I had the non vac metal orangish one. So I have the vac metal SAGA C-3PO, Maria in the middle and the Forcelink 2.0 c-3po. So the ak is shinier than Hasbro gold, but far from Vac metal. You can add a thin coat of floor finish, no more that one coat, or it'll just look like clear coat over metal paint. The floor finish will also protect it.
Also the Gold can be mixed with the Aluminum, to make Champaign, or in metal terms a nickle finish. As with this concept IG-88. I just had to go a little heavier on the gold.maybe as much as three parts gold one part aluminum. I need to get silver, to see if it's any different from Aluminum.
