I had a lot to say about a similar product called "CerMet", also a ceramic-based oil additive.

The claims are so good, I wonder why it isn't used in the OEM market. It would sure help with a lot of issues the engineers are working on... emissions, fuel economy, etc.

Also, this compound claims to seal all the nooks and crannies of the combustion surfaces. I should point out that these nooks and crannies hold the oil that provides the lubrication on the cylinder walls. These nooks and crannies are engineered into these surfaces by design engineers, and reformed during engine rebuild by machinists who hone the surface to break any glaze. A smooth finish as claimed by CerBond is undesirable for cylinder walls.
