Ouch, never thought about how a body would weather small a/c.
The "easter egg" effect of the early TPS would look like some sort of mange at 1/350 (and worse at 1/700). For "bright" schemes, it would almost seem like you'd have to "reshoot" the decals, printing them faded to get the overall effect reduced.
Heat effects, soot & grime, would seem like a very repetitive job under the magnifier. Dunno, might be rewarding to detail each a/c as an individual a/c kit--if possibly tough to sustatin through an entire 80-90 aircraft wing.
[strangled noise] Just thought of what it might be like to replicated the scorched paint effect on all-sea-blue a/c from the 50's at 'carrier' scale (and it's an effect I can;t carry off at 1/48 or 1/32, wouldn't know where to begin at 1/10 the size <sigh>).
