:think: I read today in Performance Racing Industry magazine about a company that produced ceramic bore coatings for automotive racinge engine sleeves. IRL, Indy, and Nascar, where touted as their users. Super news to me, they listed email contact names but no web address, repeated attempts at calling and emailing have yielded no response. Again, any experiences out there? Seems like new ring coatings or base metals would be in order, as well as respecifying ring groove surface finishes and concentricity. Looks like hey are putting the coating on Fe sleeves,(no Punny for my bunny). Still kinda weird, I can see bonding it to aluminum but iron? An :think: yone?
