Ditto all of thwe above. As you add more and more coats, it will go on, and must be put on, thinner and thinner. I hand rub and use steel wool about every other coat. In addition to wiping the steel wool frags off, I go over it with a large refrigerator magnet. It always seems to pick up a few stray pieces. Also, you can get tack cloth at the paint dept in the lumber yards and home supply type stores.
