Fasteners corrosion

[SEBASTIANOFA]

Will the original threads of modern cars rust over the years if anti-seize is not used? I don't think they put anything in the original assembly but I imagine there is still some air in between

That’s a lot of stuff mate, as for the materials there are no problems because I will take new and original bolts, so I will stick to what is foreseen in the workshop manual, my doubt concerned the internal corrosion of the thread, I imagine that when tightening a part of the internal coating comes apart and expose the metal of the thread to the air. it must however be said that the air inside the thread is minimal, so I don't know if it can be a problem or not, I wanted to use a special grease in order to remove any doubts, but I don't know how to move in case I should find some rust. How could I clean the thread without ruining the tolerances?
rust encapsulator inside the thread would work but I think it would create too much friction material
