Depends upon amount of poly to thinner used in the product you used. I make my own wipe on poly using 50% poly and 50% mineral spirits. Two coat of this equal one coat of poly. Some commercial brands have as much as 70% thinner(MS) and other additives. Remember wiping on a thin layer of finish still the more you add takes longer to cure. Still want to avoid using too many coats due problems curing or cracking when fully cured.

Most full strength clear finishes reach 90% cure in nine or ten days and can take full thirty days to cure. Most people using oil based poly thin it 10 to 15% before application so all about temperature & humidity.

Know you used 1000 grit wet/dry paper you do not say whether you used water or oil to rub out. If used water helps if put a few drops of dish washing liquid in the water to break surface tension. Have used mineral oil & sandpaper to rub out a finish too!

Bottom line sounds like applies to much pressure while sanding without enough lubrication.
