Paint for wall shield- high heat?

Finally got the chimney taken down, new hearth built over the weekend and getting ready to frame for the new wood stove.
We're getting a piece of steel cut to use as a wall shield behind the new VC Encore. We would like to paint it. Do we really need to use high heat paint? There is a heat shield on the back of the stove already. Previously there was a brick hearth behind the stove- which is also gone now.
Cannot wait to get this stove in and fire it up!

We went with a high heat primer and paint. Used a burnt copper color (engine paint found at Auto Zone)on a cut piece of diamond plate steel. Looks good
We passed inspection with flying colors We've been without our stove since last October when they found problems with our connection and 2 different companies could not budge the liner. Demo'd the chimney and just had a new double walled insulated chimney run up the outside of the house. When the weather gets warm, we will box it in to hide it. Made a few break in fires in the new Encore. She is a bit intimidating. I think our wood is almost too dry since it doesn't take much for this stove to get to "cruising altitude" but then she goes up way too much too fast. I know it will take awhile to figure out how to find the sweet spot. Just 2 smallish splits on the coal bed had her pushing 750-which I had no intention of reaching just yet. May have to mix wood. And now of course the weather is going to get warmer.....
Will post pics when I upload the stuff from the phone...
