I have quarter-cut oak with two coats of oil-based polyurethane, nothing else. I wanted to use the Rejuvenate restorer to give it gloss. I followed the instructions meticulously, vacuuming and cleaning first with Rejuvenate Floor Cleaner. I rocked the bottle gently four times and applied the product with a microfiber applicator on the head of a sponge mop. The inconspicuous spot I tried first in the closet looks ok.
See the picture for how it looks. (https://goo.gl/uPKORl) I tried a second coat in an area but it looks the same. Can you recommend something to fix it?

For these cases, it is recommended to use a wood restoring putty, it dries very quickly with a solid and durable finish. In addition, it can be used for both indoor and outdoor use, and also has 8 different colors to choose from.

You have a beautiful floor. I suspect that the acrylic poly-urethane that you used was not cured enough for the second coat to look as good as it should. Some finishes take a few days to cure before adding another coat. I hope that it will look great after you allow more time to cure before you apply another coat of finish.
