Has anybody had there header coated to cut down on heat.I have the so famous piece of shit V&H exhaust that is rusting down at the collector.I had thought about having mine coated to help with the rusting.Any thoughts about that out there.

Never done it to motorbikes but ...
With coatings on exhuast manifold, turbo shells and dump pipe
Detroits in semi's ran cleaner exhaust plumes with less conrod failures
The Cummins generators got both manifolds, turbos and entire exhaust coated
and consistently showed lower temperatures inside the containers.
The coatings were still going strong after six years on the semi's. 
We used Jet-Hot sterling.
This product stops the heat getting out, i.e. the heat is trapped inside the tube or whatever.
But if the problem with the V&H is a thin wall tubing, any coating to
protect them from road spray would have to help.
But I wouldn't bother coating partially rusted systems. 
I'd coat them new prior to install.

Jet Hot will do used headers, they clean them inside and out, then coat them...

I used Griots high-temp paint on my formerly gnarly lookin' headers.  Just painted it on with a foam brush, let it dry, ran it up to temp, and the headers look great.  A nice satin-flat black, no streaks.  Might be worth a try for you.

I used Eastwood's brush on coating on the manifolds on the SBC in my 54 Ford.  The truck has hauled everything from 2200# of donkey shit to my 19' Maxim, year round. Many times sustained WOT for miles.  After about 4 years there is some rust showing thru in spots (they were ground bare).  Great performance IMO.

Jet Hot is the best, but the brush on coatings are decent if you're on a budget.
