Cylinder bore glaze bust - how

[lofty]

i saw the pics of a before and after on F7 block and its looked fantastic. How does this process get such a precision hard wearing finish (assuming it is?) what would the process cost exc. refitting etc - purely the glaze to a bare block?

glaze is a phenomenon you get after long service life.

The finish (honed) isnt particuarly hard wearing, its there to promote sealing. The copious amounts of oil from bore sprays keeps them in very good nick.
