If you can't undo it, I would mix up something right and recoat. Any chance of cooking the part at say 150 degrees for a while? Again what you wrapped would matter here. But heat could help it get a bit more cured.
Boats use polyester resin and in some situations the laminating resin remains purposefully tacky so that you can do multiple layers without sanding. They put a finish coat over that and it works fine. You should be able to do the same with epoxy, the key though would be to get even coverage and not sand through into the tacky stuff when doing finish work.
I would probably try to redo it completely myself.

I didn't think about the acetone, but that sounds like a very aggressive resolution but maybe one that is needed. I wrapped the cheesy carbon fiber dash pieces, silver plastic piece around the gear shifter, and the silver trim pieces on the inside door handles. "Tacky" is my finger will stick to it but nothing comes off on my finger. Moving forward with the correct ratio is what I'm really wanting to do but I fear of making it worse. In theory I would think that you could correct the ratio 2:1 epoxy hardener and thin epoxy resin contine to lay down 3 to 4 layers, let it cure then sand it back but not to far to where you start hitting the tacky layer, but that is just my theory. I think i'm going to keep pushing forward with the ratio corrected and it that doesn't work then I may try to rip the carbon fiber off (if thats possible) if not then it looks like I will be buying all new trim pieces and learn from my mistake.
