I would like to say that I am primarily asking about the color of the rock. Basically, king n c has SP011 Afgan Cave and i think there is a SP007 was a Iwo Jima cave. Having not seen SP007, was keen to find out more...
I google around and below are the photos I found. First is SP011 and the other is SP007.
So, I ask one more question, is there a temporary color paint that I can apply on the Polystone that can be easily washed off? This I think will help greatly. Again, sincere answer please, it is Easter week and so, be good whether you have taken a Passover meal or fasted or not. Thanks as always.
Thks,Chris
Chris, lot's of thoughts here, just going to rattle them off:
A) SP7 vs. SP11: They may be the same color to begin with. Unless they are both next to each other under the same lighting, one can't tell. I don't think either was matched to an Iwo or Afgan color, but rather just painted in an approximate base color, then drybrushed with a lighter grey.
B) These date back to the Foamtech (iirc) era so they are likely not Polystone, hence not able to stand up to a good washing/scrubbing to remove paint. They are likely expanded foam like the original Normandy Village. They are going to have random hollow spaces on the interior and be somewhat fragile to handling to begin with.
C) Easily washable paints probably exist, but they have a limited range in color so you are going to have to do a lot of mixing experiments to get the color right once you decide what color you want.
D) If you want to repaint one of these don't go into the the project thinking you are going to wash it off later. Research the color & commit.
E) There is definitely color data on Pacific Rim volcanic geology out there, as taking these measurements is one of the things geologists do. The data would be expressed in Munsell format, which is one of the keywords you would search. Find the data, I can help you determine the color from it. As for finding the data, you could try writing geology professors, Google "Munsell & Pacific Rim volcanic", follow the trail.
However, there must be a few documentaries out there where veterans returned to Iwo & you could just approximate it from that. Also keep an eye out for Iwo dios done by Japanese modelers as they might have a head start on all this
