This is the internet...a quick "google" of performance ceramic coatings will give you hundreds of examples of where this product has been tested and proven. Like i said before, your example does not mean or prove anything if no before/after comparison is done (this is how i do my testing). Like Silv.is trying to explain and i have also stated earlier in this thread, the coating is done on the turbine side to aid gas flow....not too keep things cool around it, thats the job of heat shields etc.
Thanks for the acknowledgement of our work...its good to see the time, effort and dollars paying off
