I went through about 2 packs of 220 sandpaper and the same with 400 when I ran out of 220, and as you can see there is still a dark spot in the center.

It did form a slurry when I lapped it which is a milky white with almost a faint cream tint to it. Dried on glass looks kinda light gray.

I just ordered a Coarse grit DMT so it should be here in a few days. Also got a Norton 4k/8k and a prep stone. Hopefully that will be enough to sharpen up the older razors I found at the antique store. Most of the edges are in pretty good shape.

My sharpening arsenal will consist of the 4k/8k, whatever this stone is, and I ordered one of those wool/cotton strops and .5 dia spray and chromium from SRD.
