Single cylinder glaze honing?

I have pulled the heads of a small block in the car and the cylinders and bottom end in general are in very good condtion with no ring ridge and cross-hatching still visible. I notice that bore #8 is a bit glazed and want to break the glaze with the bottom end still assembled. Long in the past I have done this with a piece of 220 wet-or-dry moving around in an angular pattern (not sure it did any good but made me feel better!), but figure there may be a better way. Has anyone ever used any sort of glaze-breaker/hone with the pistons still in? Any other clever ways to do this? Tnx in advance...
