I would use Evapo-rust then you can paint it with the paint of your choice.

I really like this evapo-rust , It is reusable if you can contain it.

Perfect for small parts.

With the bigger parts you lay a rag or towel over it and keep it damp.

Some of the gears I clean with it sat out for several weeks with no signs of flash rust.
