I am re-finishing an old oak dining room table. This is my first time attempting to refinish furniture. I used a lamb's wool pad to apply the poly, and even though I thought I had rinsed and cleaned it thoroughly, there were TONS of fibers stuck in the poly. I picked and wiped out so many, but after it dried, I could see a thousand more fibers. I have lightly sanded a couple spots, but now the finish is grey-ish. I need lots of help. Can anyone tell me if there is anything I can do, short of starting from the beginning? Any help is greatly appreciated.
