i wish i new more my self - but if you think about it think about the nonstick cooking pans we have- they really work-(i know bad choice in a way)
but they do take heat with out flaking off ,and we have a lot better technology now than we did
so the technology with a coated piston,and bearings sounds like a great thing
i just worried about the coating coming off the bearings,and leaving a different, size ect..
