Hello- I just wanted to check something here:

The rules say:

"The application and/or use of any painting, coating, plating, or impregnating substance (i.e. anti-friction, thermal barrier, oil shedding coatings, chrome, anodizing, etc.) to any internal engine surface, including intake manifold internal surface, is prohibited."

Fair enough, but I am assuming that OEM pistons that come with a skirt coating are allowed.

If so, if you are making replacement pistons, can they have an equivalent skirt coating? I'm thinking no, but has this been discussed?
