It is not powder coating. The abrading coating imbeds in the piston skirt material and just wears out just like any other piston skirt coating. If you are having a blow-by issue, look at your rings and cylinder wall finish. Never had an issue with their coatings.

I am not saying there is anything wrong with the coating. I think it is a great process to overcome cylinder wear without having to bore the block. I am just trying to learn what to expect during break in. I do not want to pull it apart if it is not necessary. The engine has barely been run for 20 minutes over 3 days. Maybe the rings have not seated in 3 cylinders but will with more time it will. My biggest concern is the blue smoke coming from the vacuum pump breather. The other concern is running the engine up to full tilt while on jack stands as part of the coating break in procedure.
