I read an article some time ago about re-surfacing/flattening stones by spreading a grinding compound on a piece of plate glass and rubbing the stone over it. Anyone have experience doing this? What kind of compound? What about cleaning the compound off of the stone? Any help/advice would be appreciated.

Thombrogan a very knowledge poster on this forum suggested to me to use wet-dry 220 grit sandpaper. Worked great for me but I would buy several pieces cause the abrasiveness is worn away quite quickly.
I would recommend you try it !

IMO, it's a perfect job for cheap ebay diamond hones which suck mostly but do THAT job ok. on soft fine grained waterstones, i'll hasten to add,
*not* synthetic stones made from carborundum or silicon carbide, take THOSE to a piece of ugly sidewalk on a nice day with a beverage by your knee..
but once THEY are flat, (or a new 3$ china stone) the occasional brush up of your other stones is nearly automatic. keep a cheap rock by the sink, wash em and lightly flatten as necessary, part of the maintenance, and you don't even notice it.
seriously i find it necessary to own the 'King' brand, or similar, very cheap UNFILLED (no oil) carborundum stones to save wear on everything else. using a coarse natural stone, like an aoto perhaps, to ease a better stone isn't wrong.. or even rubbing a pair that are similar together (belgians are so hard that works better than other ways) ..
rocks flattens rocks. you can do it on glass with abrasive paste, or sandpaper, and it's easy to presume flat with glass... but the issue isn't the flat bit. 'flat' is easy enough, either way. what is the point is, how much time you spend doing it, and how tedious it is.
if you'll just rub your rocks together a bit in the using/cleaning wash-up process, you never need to think about it... and they sorta automatically very lightly chamfer the sharp edges to make them less fussy to use. might not be ideal but it's brainless..

Your talking about Carborundum powder you can buy in various grades from many auto parts stores. Ideally a small quantity is spread with a modest amount of water on a pane of glass, then flatten your stone with vertical and diagonal strokes. I prefer the XC diamond stone for stone grits finer than 1000 and a SiC flattening stone for stones coarser than 1000. Sandpaper in 600-800 grit is another alternate choice for less dished stones.
