This morning I went and got some steel wool. I was in the middle of scuffing the poly when my wife came up the stairs and asked what I was doing. I told her I was trying to get a couple of bugs out of the poly. It wasn't a lie, there was a dumb fly that got stuck on top of the surface. I got it out and vacuumed my mess. I laid down the last coat so we'll see how it looks tonight. I almost created a huge problem though. The poly from yesterday was pretty set up but not when a fat kid knelt down on it. I didn't kneel on it anymore after that. I'm not going to walk on it until Sunday.
