Hmmm...   ...ok.


I've known people who used moly rings who didn't use anything any 
coarser than *600* grit to prep cylinder walls.   Worked out 
nicely.  These were high performance larger displacement engines.   I 
always used that 400 grit sandpaper wrapped around the glaze buster 
stones, with plenty of penetrating oil.   It left a satin finish to 
the cylinder walls and moly rings usually seated well in just a few miles.


I'd really like to see what those cylinder walls look like...



When it comes apart, could you take a photo or two of the bad 
cylinders' walls?
