Painting fuel tank?

I have a nicely painted interior and now debating whether I shall paint the fuel tank (except bottom skin) or not.
If I paint it, it would much better integrate in terms of the look, in case I opt not to cover the tank with the carpet.
Not painting the tank is obviously lighter and might be much more desirable in case of a leak. In that case I would go with the tank carpet.
What I already painted is the fuel tank filler neck.

So I am interested in how other builders did it? Paint the tank or leave it with shiny Alclad?
Thank you for your opinions and experiences.

Painted it ... and then covered it with carpet.

I painted the filler neck and left the tank unpainted. I have a light material with a rubber back covering the top of the tank. Just personal preference.

Polished mine. My website holds plenty of pictures.

I painted it to match the interior. The Vans interior package carpet covers the top and one side.

And the seatback hides the front.
