I have an oak dining table that I ruined the finish on years ago with a nasty cleaning product. It left the finish sticky and gummy and not very nice to look at. I actually lived with it for the past year with tablecloths, but really missed the wood. So, I stripped it with Citristrip, restained with minwax Provincial stain (these steps seemed to go well). I then used two coats of fast drying polyurethane in a satin finish and it looked well. Everything I found indicated that you might want to do a third coat on a high-use item. Still looked good after 3rd, but saw paintbrush hair and a small curly fuzzy that dried in finish. At the advice of another, I sanded that coat to get rid of imperfections, and did another coat of urethane (BIG MISTAKE) it is way to glossy now and does not look near as nice as it did. Do I need to strip everything again and start all over or is it possible to sand just through the polyurethane and begin with it again? Maybe I should try the wipe-on variety rather than brush-on. I am really unhappy with the way it is now.
