Ive noticed the problems with this kind of detailing.... Its addictive I'll tell ya.... I did mess up on the port wing and had to break out the airbrush and touch up one area.... I cant use an eraser on it either as it takes off the damn paint....
The way I did it was to first hit the lines with a chisel pointed mech pencil, then dabbed a brush into the powder left over on the sandpaper and lightly brush it on the lines.... Some of them I went too heavy, some too light....
Follow on brushing made them relativly even.... I now have the wings lightly taped over to prevent overspray when I start the RLM82 camo on the fuselage... That tape will also remove some of the extra graphite on the panel lines and tone it down some....
I didnt want to spray the clear Future on the wings before I sprayed the whole thing, to keep it uniform...
I also went and diffused some of the camo with some brushed graphite in certain areas to give some tonality to the camo and to mimick, albeit rookie level, the mottleing that Wayne has been demonstrating... Also some filth...
It worked to some degree I think...
