Hi Ed!
Long time no write!
Yep, researchin the heck out of it. As far as this particular question goes, I found a string on another Forum (Hobbytalk I think), that discussed this very issue and the consensus seems to be that A glosscoat/clearcoat will erase the effect.
So now... I've got gloss white (cheapy home depot stuff) down as the base and am applying the Aztec Dummy masks (TEDIOUS STUFF, but looks frikkin COOL). Once that's all on, I'll put a coat of Tamiya Insignia White over the top. This should give me a slight grey color overall, with the aztecing in white. Then Glosscoat/Decal/Dullcoat.
I'll borrow a Digital Camera once the insignia white goes on, so you (and everyone else) can see how it turns out.
Bet your looking forward to building yours huh?
Mike
