Long story short: my pool has one return using metal pipe (black steel I believe) and it's end is under water. It rusted under pool water (chlorine). I would like to try painting it before more expensive fix. Any paint for metal under pool water is recommended? Thanks in advance.
 
I think it will be easier if you drain the pool down below the pipe.

But if you use this let us know how it works out…

 
Put a rust neutralizer on it before painting. The neutralizer needs rust on it to work.
