this thing is not letting me upload the after shot, so I guess that's that - sorry folks.
I get the feeling this is a really tricky one to nail right.
Yeah it's tough, ultimately you need more specularity in the paint, polishing diffused matte paint doesn't accomplish the same effect (though it looks better that non-polished). I doubt the MK42 will look right, those pics are well shot but the paint job looks too diffuse still, but I'd love to be proved wrong. SDCC will be interesting, hope for some updates on the 42 and from eFX.
