I had the table finished and didn’t like the imperfections in the top, most due to crevices in the veneer. It was finished with GF High Perf gloss, which I sanded and recoated with satin. Thinking I could build up enough coats, but after 5 coats each time I sanded & couldn’t get anywhere. I tried wet sanding with 1000 grit as well as rubbing out with steel wool.
ThenI got the idea of grain filling. I had problems right from the start with lines that formed in the Aqua Coat I could sand off, but each time Imapplied finish they reappeared.
So I sanded everything down, filled the grain, and re dyed it. Disaster!! So I gave it a coat of shellac and redyed but no luck. I’ve thought about a gel stain.
I think what’s happened is a I sanded too deeply into the burl.

Wow. I feel for you, but no I have no solution. I can only speculate that you have sanded so much that you have reached glue impregnated veneer which is keeping the dye from penetrating. You don't mention what type of glue you used. Hopefully I'm wrong and another member can provide a workable solution. Good Luck.
If you sanded too much noting will save it but if not, use chemical paint stripper and remove all finishes and see if it all comes even and then, a light sanding or better, cabinetmaker scraper with a light touch may bring it back to bare wood.

Ouch. It does appear there was too much sanding. Not what you wish to hear, but prepping it for paint might be a solution..
It looks like you might have sanded through the burl. If so, there is nothing you can do. Paint, lighter fluid, or inventing a time machine are your choices.
Exactly. And I was being careful. I don’t know what the heck happened but after the Aqua Coat I could not get rid of the lines, even after 5 coats of finish. They weren’t ridges just lines that seemed to project through the finish.
I applied the filler over a sanded out finish. Guess that was my mistake.
Fortunately I had another veneer panel I was going to build a matching table.
Here how I took it apart:

Got it apart successfully and found the original patter for the veneer field.
