I also read the FAQs....the write up done....and watched the video. I'm just curious to know about the polishing of the journal surface. If it can't be done...so be it...but if it can...what benefits if any are had after the process or does the polishing ruin the process in itself. Thats the main reason why Im asking and stating what I've posted. I'm not on here to argue...I'm trying to get more info since you've had this done and you've obviously spoken to the WPC team.
