Heh, I'm the other way on the dot filters.. I think it's a fine armor weathing technique (not one I care to do, but fine, none the less), but I think it's a bit heavy-handed for aircraft that aren't based on "primitive" fields... Of course, that's gonna depend on how grimy you want it to look too.. Your call, at any rate, I'm just sounding off..
Gotta gree about star & bars... Perhaps a little touch-up with the base color and a brush? That's what I'd do anyway..
Stik, you needin' those small insignias for a T.O. 114 SE Asia Camo? Or will the larger ones from a NMF bird do? I've got some spares from the F-80.. Or were you just askin' P-38 dude about replacing his?
