Rust on the bottom Pics

I have noticed that the straps that hold up my gas tank are rusty but never really thought about it. Yesterday I was looking up under it and kinda got sad. I have noticed a little rust here and there but never anything this bad. The car came from up North so I guess I should not be to suprised.



This is behind the back wheel




Its not going to see anymore snow or salt but this looks bad doesn't it? Is there anything cheap and easy that can be done?
