[stone]wet look

["George Graham" <georgergraham@zzzzzzzzzzz>]

Welcome John,
Sounds like you have some beautiful granite. The tips I can offer are old
fashioned, but may still help.
The tiny lines between crystals all always a problem in big crystaled
granite. To lessen their impact I would do a final buff on brown and reddish
granites with red cement coloring powder mixed into the pure tin oxide.
Black powder was used on all black granites. The idea is to tint the white
residue left from the tin oxide
I never honed up to 3000 grit. 600grit carborundum powder is a fine as I
went, followed by buffing with a hard felt pad and a little water with pure
tin oxide. The company I worked for did everything the old way. Change was a
dirty work, so I learned to get a wet\high polish with the tools at hand.
Doing things my way, I know that black granites are the hardest to polish. I
spent 3 times as long with the tin oxide on the black as I did on the other
colors. Honing up to 3500 may have cut down on the buffing time. It could
not have hurt, for you can't sand down granite to much!
Your use of tung oil makes me cringe because its has pounded into my brain
that oil should never be used on granite. It will only make a stain that
will never come out, or it will give you a wet look that will fade with
time. Especially if its outdoors. Old ideas die hard.
My personal opinion is that the natural  lines around the crystals of
granite are just part of the stone and don't need filling. Going to the work
of filling the lines could be a lot more work , depending on the complexity
of your piece. That's for you to decide.
Finally, I hope you figure out a way to let us see your piece. Its sound
very interesting, and we are an insatiably curious group!
