Hey Pro’s on this quartzite sample I’ve exhausted every Polishing possibility that I know of from 20 yrs. Of experience.
 I have tried polishing with every miscellaneous polishing buff pads wet & dry including after diamond honing after 8,500grit then tinoxide  compounds, including the recommendations of mb22 and mb20 with a pinch of tinoxide. And 2 other tinoxides by them self.
They All come up short of 100% full polish to blend to make it acceptable on a slab wall job for a contractor as far as I’m concerned.

I have no doubt that among the Advanced pros if you saw it in person you would agree the finish I’m trying to achieve is not there yet.
Of course you can’t tell by the pictures as you know this is one of those things you have to see the sample in person but it’s not there yet.
Any other advanced ideas?????
