I like it as is as far as paint goes. I wouldn't put salt on it, however. Unless it spent a LOT of time down on the deck, it wouldn't accumulate much. IOW, it wouldn't look like a car that's been driving in Ohio in the winter
. OTOH, it would stay wet a lot with accumulated mist and probably fog sitting out on the ramp. This would build up into drops while parked, which would run down the sides. This would give you a lot of vertical streaking in the exhaust stains on the fuselage side, from the paths left by the water drops running down.
Now don't take this part the wrong way, because I'm fully aware of the amount of work you've put into this part of it, but IMHO your rivets are WAY too big and visible. On the scale of the plane, they're all almost as big as car lugnuts. In real life, a rivet head is only about 1/4" wide, which is only 1/3 to 1/2 a pixel at 1024x1024 on most fighter skins. Thus, by making your rivets several pixels wide, you've made them 10-12 times bigger than reality. IMHO, therefore, rivets shouldn't be more than 1 pixel, and even things like dzus fasteners should be no more than 2 pixels wide. But this is just my opinion. I really LIKE how your rivets LOOK, in that you've captured the appearance of a countersunk fastener very well. But they're just way too big for my taste.
