I vote you paint it but only if you promise that you will never show it to any of the other members' management - especially not mine. The last thing I need is to have to start painting things.
If you ever have a fire in there you will regret not using high temp paint. On the other hand, if you ever have a fire in there, you will regret a lot of things a lot more than that!
Personally, I doubt it matters but why not! Since you already have the paint, I'd use it.
