Enamelled Exhaust Manifold

[NeddyBear]

Sometime back we had the stock exhaust manifolds Thermal Ceramic coated to cut down on the underbonnet temperatures which worked perfectly.
Recently when at a 4x4 show I see a Land Cruiser that's had the stock manifolds coated with Enamel and I'm wondering if anyone knows if the Enamelling product has the same kind of thermal barrier qualities.
