I have searched all over the net and nothing covers my question... When I add that little molding to the baseboard over the laminate wood flooring (I guess it is called quarter round trim?) they say that you have to nail them in, but do they cover up the nails and paint over them or something? Because I never see any lines or nails on that little round part that usually goes on the bottom of the base board.
You can use a finishing nailer, if you have one, which leaves the smallest hole. If you don't have one then use a hammer, small finishing nails, and a counter sink to set the head of the nail(s) below the finished face of the trim, then use a colored putty stick or wood putty to cover the hole over. Most importantly, pre-drill your holes in you trim(to prevent it from splitting and don't nail down into the floor, but back towards the wall. Nailing straight down into the floor will prevent the floor from moving, since it's a float-able floor.
