Manifolds...Paint Or Coat?

Five years ago when the Dart was redone the body shop painted the exhaust manifolds. They are holding up good so I asked him what he used. He said POR 15 high temperature paint. Summit had it and says:

"POR-15 offers several high-temperature paints that you'll definitely warm up to. If you've ever painted headers or a manifold, only to have your work start to burn and peel off the first time out, then you need to give POR-15 high-temperature paints a try--you'll never need paint again! POR-15 Factory Manifold paint is capable of withstanding temperatures of up to 1,400 degrees F. It will maintain its durable cast iron color without burning off or discoloring and resists cracking, chipping, and peeling. POR-15 Factory Manifold paint is your defense against extreme temperatures."
