What if I don't wait?

That was way more information than I needed. =:-0

That's a perfect straight-line if I've ever seen one. Nope, not gonna stoop to that level, uh-uh, nosirree.

Regarding your question, I would be concerned that if the Danish oil had not had enough time to fully cure, the poly may not adhere well to the surface.

I've gotten very good results with Danish Oil followed by three coats of Watco wipe-on poly on cherry for my entertainment center. My normal finish preference for cherry is polymerized tung oil, but the entertainment center was too large a project to make that finish schedule practical. The wipe-on poly doesn't leave that coated in plastic look, and followed with a good coat of wax, the figure of the wood really stands out.

When I was doing test pieces, I found that the Danish oil imparted a better effect in pulling out the figure of the wood than any of the oils I tried. I didn't want to use BLO because I was not wanting to take a chance on the oil yellowing over time.
