Thermal barrier coatings

The coating is only as good as what's underneath. The coating does help prevent hot spots, but the issue you will see is detonation. The aluminum underneath can dent, and the coating can come off at that point, ring lands can collapse, etc.

I'd definitely use the anti scuff coating on the skirts no matter what!

When I first saw the eroded surface detonation came to mind and then right on the heals of that thought was the thought that detonation that bad would be making a mess of the rest of the lower end, bearings would show the damage as would the piston crowns and the "show and tell" is not there.

He's working with his engine guy and will think of some thing...........I'm just trying to learn some thing new.
