But Golly, you were the one who, when those first pics came out, was saying: yeah, there are four rows of hinges, but it looks like the lids are very narrow and that two lids (with two hinges) form a cover for one square cell. Lets now not get into the point that's extremely unprobable as it'd make whole construction more complex and unrealiable (if just one of two hinges get stuck, youre screwed), this latest pic proves lids are indeed squareish, which means one hinge - one lid - one cell. Unless you want to backtrack and null your own previous admission there are 4 rows of hinges, I don't see how you can claim there's any other number of cells but 32.
I agree with you brown part of lids seems to be on the outside. For now. We have to rememeber the whole thing is still being furnished. It very likely is, like popeye said, a primer color. As for application of ram paint, i find it unlikely, as radar returns from the top surface aren't going to account for much, especially as there's BUNCH of other stuff on the ship to give radar returns, much bigger than those lids. It would just be too pricey for what it offers. Actually, I doubt there is much RAM used on the whole ship, for that matter. It would be like using a finger to try to seal a meter wide hole in the wall.
