Those are impressive, Eric.
Today, I started laying in a bit of my weathered white on the prop
And over the tail
The worn look was accomplished with a base layer of medium grey, highlights of white, and a thin top layer of white grey. I will then mask these spots for the white lines along the rudder and the hakencruz on the tail.
I also got some weathered yellow laid down
For some reason, the top of the wing photographed better, but both top and bottom are equally shaded to the naked eye. This was a base of sand yellow (a light brown), highlights of aged white (an ivory shade), extreme highlights of white (very sparingly) and a top coat of rlm 05, gelb.
For both of these effects, I've tried to put emphasis on the contrast, even overdoing it a touch, because I know once I lay in the greens, the pale colours will lose their contrast in comparison. My gloss layer will also darken things up a bit, thereby decreasing the contrast as well. I don't want to have weathered my white only to have it come away looking monotone like a decal, then I may as well have applied decals.
I also have my main wheel spats painted.
So, I'll give all of this a day or two, finish building my other cannon, and then apply some masks. I want to make sure that paint is really cured nicely prior to laying my masks down. Before long, I should be able to finish out my primer layer and start shooting some 65.
