Quite a lot of le exposed rivets there. Anyone care to explain? Could it be that RAM coating hasn't been applied or some other reason?
If you want to see you can always find it.
Zoom in, rivets are everywhere.
Some people will argue that this is a prototype, but the construction did not change, in production items the rivets are still there just some of them are covered by thick paint or tape.
Production F-35C, about half rivets are covered. The light condition is not ideal to identify areas too bright or too dark.
Why j-20 isn't doing it? We know F-35 uses mostly composite skin which has a very unpleasent electro-static characteristic must be dealt with.
