outstanding job on the weathering on ur zero! impressive cant wait to see ur chipped national insigna, i have see some people cut off small pieces on the decals and put it on the aircraft, some comes out good, some comes out ok ok, but i like ur idea to recreate the national insigna by hand which i never tried it before since i was not sure how to do it on the US national insigna.
