Has anyone tried this stuff? I understand the general principle is to inhibit heat absorption into the piston top or parent metal. It might help keep exhaust heat from transferring into the port walls.
I had been wanting to try it, along with another product they have that is supposed to improve heat transfer, when I was playing with air cooled motorcycle engines.
