Hi temp header coating

Last month I bought a used "Rod's Header" from a NATO member. I am thinking of sending it and my turbo to Swain Tech Coatings to have it coated White Lightning Exhaust Coating. They say it will reduce radiant heat in the engine compartment by 35-55%. Does anyone have any experience or advice concerning this?

I had a thermal coater header on a previous project car and the coating did indeed help with under-hood temperatures. I'd also recommend wrapping the downpipe if you're really trying to reduce under-hood temps. This alone made a significant difference on my last turbo car

Plus, correct me if I am wrong, but having the thermal coating will also keep EGV/Thermal energy higher in the header/turbine housing. If you do the downpipe, it too will help exhaust gas flow velocity and contribute to a more efficient pressure ratio.
Lost in translation..........

John B, thanks for the confirmation.
88Boostedbird, TurboAlpine said something similar.

John B,

Did you have any problems with the coating lasting?
Who did your coating?
Would you recommend them?
