I have some knowledge on finishing, but with this I am stumped. My boss and I are re-finishing the bar top at my work, sanded it down properly to a 320. However, we could sand for days and there still will be uneven surfaces because of the condition of the bar before we began. 50% of the bars varnish was all gone and bare wood was subjected to many years of spills and cleaning products.
Our steps and products are as followed.
30 year old White Oak

1. Gradually Sanded down to 320
2. Amber TransTint dye applied with a water base (very light coat)
3. Sanded it back With 320
4. Reddish Brown TransTint, a tiny bit of black TransTint to darken it then more Amber. A pretty heavy coat (At this point the color was great. A little peach-ish, and I know that dye looks different un-finished. However it didn’t match the back bar that is a 100 year old red oak that has been subjected to years of tobacco. We still needed to make the grain dark. I tried on a sample piece of white oak dying the grain first with black, sanding it back, then applying the dye, but the color came out wrong every time. Not sure why on the Sample it worked the way that i did it below and with the bar it did not.
5. Applied a 1lb coat of bullseye sanding sealer
6. Scuff sanded it
7. Applied a mix gel stain of 80% General Finishes brown mahogany and 20% General Finished Java
8. Scuff sanded it
   This is where we are. With a super orange bar. We just want to cool it down a bit to bring out the amber.
   I heard Raw Umber universal tint is the way to go. We really dont want to have to sand it all the way back. And in my opinion the grain should be darker also. So was thinking tint a dark stain to do both things. Tone the orange and make the grain darker. But I dont know what to use and where to begin. My color theory isn’t the greatest other than I know green/Blue tones down red. But with the yellow of the amber If we used blue would it make the more amber figure green? And one thing we don't want to have happen is adding a tint to the top coat and it muddying up the wood.
   I’m Lost...
