Can anyone recommend a good, but inexpensive anti-rust paint that is in auto parts stores that I can use to paint the chassis, brake and fuel lines (some are slightly surface rusted, one fuel line above the frame on the driver side between the doors is starting to get flake rust, but is not leaking), and the rear differential cover (spots of rust)? I noticed all this last night when I was checking stuff under the truck.

any specific one for cars that does not eat the metal to get rid of rust I can use on fuel and brake lines? Thanks.
