I'm sorry for reviving such an old thread but while looking for CrOx in Bulgaria I found a distributor of Kremer. I've read all posts here and they are all positive. The only thing that worries me is that CrOx is usually 0.5 micron while the Kremer one is 0.3 micron. I'm going to be using it for refreshing my straight but later on when I get my lapping film also for honing after the 1 micron lapping film. Is it suitable for this or should I get a 0.5 micron one? Thanks!
