Personally, I kind of wish that the "corroded" paint jobs, that come with the Raider ship-kits, were available separately.
Actually, that's not entirely true.
The current "corroded" paint jobs just look a bit brown and splodgy.
It'd be nice if they were far more detailed, with different coloured hull-plates and visible rivets, wiring and other greebles.
Normally I see a worn paint job as a "badge of honor" but there are some cases (such as whenever I fly an Annie) where I feel like the ship should look like an old junker all the time.
