How do I remove yellowed areas from epoxy countertop?

I painted the 2 counter tops in my bathroom to look like marble. Then, I made the mistake of pouring Parks Super Glaze Epoxy over the top for extra shine and durability. They looked great---at first. Within about 3 months, the epoxy started to yellow. It has progressively gotten worse. I contacted Rustoleum, but they were clueless about why they are yellowing or how to fix them. (The counters are not exposed to sunlight). I've tried bleach and various peroxides to try to bleach the yellowed epoxy. The peroxide seemed to lift the yellow somewhat at first, but now it seems like it just moved and concentrated the yellow in smaller areas so now I have much darker yellowed spots but in smaller areas on the surface.
Does anyone know how to get rid of the yellowed epoxy without ruining the paint underneath that took me months to do? Thanks

I am so sorry but nothing that will remove the epoxy top that will not destroy what you have done with your marblizing. sometimes when different products are placed on top of one another the bases are not the same,they will react sometimes negatively and I think that's what happened to you. so sorry for your issues but there's nothing you could do but start over or learn to live with it, sorry.
You said the yellowing occurred after a few months. Did it start under stuff, like a toothbrush holder, soap dish or drinking glass? Doesn't have to have sunlight to yellow. Just trying to help you figure it out. I'm sure you're ready to throw it out the window.
I think the bleaching will actually yellow it more.. hmmm
Did you ever come up with a solution to this problem?
My friend put a hot skillet on my countertops and left a burned grid pattern behind. After the shock and upon further research, tooth whitening toothpaste fixed it. I had to scrub it in and reapply a few times but you can't see that stain anymore. My epoxy has yellowed badly in large areas and I plan to try again with the toothpaste. It will of course require a lot more of it but I'll use an auto paint buffer this time. Let's hope it works.
