I typically wait 14 days whether it's poly, lacquer or Tru Oil before doing any wet sanding polishing without any issues. I have even done as little as 7-10 days but have since pushed myself to wait the full 2 weeks. IME though, the feel of the finish continues to change even after the 2 weeks, thus presumably still curing.
