[turbo6bar]

lenmommy, I've used Techline's ceramic barrier coating on a set of pistons. I ran the engine for roughly 5000 miles and tore it down (low oil pressure, mismatched engine case, really long story). Anyway, the pistons came out very nice. I was able to scrub off the built up carbon with a little degreaser and brush. It's possible this might work, if the ceramic coating creates a "charge barrier?" between metal and coating.

I also used a thermal dispersant (also from Techline). The coated cylinders were super-duper slippery. Don't know if this would work, but it sounds like some testing is warranted.
