I just completed my hardwood floors this weekend. I used Minwax oil based
polyurethane, 2 coats. After the 1st coat, I followed the directions,
sanded, vacuumed, and wiped with mineral spirits. I was overall pleased,
but it's not real smooth, and lots of little bumps, which I presume is dust
paticles. Is there another step in smoothing out the final coat, maybe
super fine steel wool?
