Exhaust paint and/or wrap

[JimT]

So as I get ready to reassemble the exhaust side of my engine I started to wonder if a high temp header paint (Like VHT or the harder to find Por-15 high temp) might be helpful to prevent or minimize rust on the bolts and manifold. While searching through old posts I didn't see any mention of paint, but I did see exhaust wraps mentioned.

So, would it be useful to paint the exhaust manifold? What about a wrap? Both?

Also, if I have an aftermarket EGT probe clamped to the manifold to monitor heat soak, should that be covered by the wrap or clamped on over the top of the wrap?

Looks and performance gains are not the goal. Longevity, maintainability and avoiding performance losses are the goals.

Any thoughts and/or experiences are welcome!
