Rod Runner Paint Touchup

[TurtleTown]

Hi,

So i pulled out my 15yr old 10 ft Jarvis walker rod and noticed the paint was flaking off some of the legs of the runners with rust (i obviously hadn't cleaned it as well as i thought before storing it) just wondering what paint i should use to touch it up to prevent it corroding away too fast now I've cleaned the rust off? Just metal etching primer and normal enamel paint?

I know its not the best quality rod but it still works so might as well try to keep it going !

Thanks Dave
