Wow, I'm surprised you guys haven't heard of this....and yes, I was posting to show that the shop I know is VERY reputable

Shamelessly stolen from some powder coating shops website:

Power Coating (Thermal Solutions)

Power coatings relate to engines/motors (cars, snowmobiles, motorcycles): almost anything with a combustion engine. Some hold heat where it's needed. Others remove unwanted heat. Some are used to reduce friction on metal-to-metal contact, while others shed lubricants. All of them increase horsepower.

Piston Coatings

Piston Coatings are formulated to provide a thermal barrier for piston domes, for corresponding combustion chambers, and valve faces. This specialized formulation withstands detonation impact while reducing surface temperatures and does not affect tolerances or compression ratios, increasing combustion chamber efficiency while increasing horsepower and part life expectancy.

Its becoming a "must-have" when building an entirely forged bottom end, just because its a fairly cheap way to extend the life of your parts, along with the other nice side effects. Shop I know only charges $25 a piston.
