Rust on Stock Exhaust (6th gen)

I just bought this wonderful bike and I love it. I want to take the best care of her. I have noticed some rust spots on the muffler section of the exhaust and was wondering whats the best way to stop/prevent more rust back there

 

Master Formula Metal Gloss followed my Master Formula Sealer Gloss. I use it on my 6th Gen and works great!

Can this be bought locally or internet only? Like who carries it?

 

I ordered off the web...I have never seen it in a retail store, but that doesn't mean it is not carried in retail stores. I would check the website and if you can't find it there see if you can get in touch with them by phone to find out who retails...if any.

easier route

Naval jelly, leave on cold pipe for 5 mins, wash off with tons of water
repeat as necessary, no more than 5 mins at a time
when rust is gone, polish using Flitz
