What is the best and quickest way? I am looking a t buying a house, but I don't like the panel walls. I want to wallpaper about 4' up and then put up chair rail and then paint the last 6' up to the ceiling. I need to know what to use to fill in the cracks of the paneling so I can do all of the above. I am not worried about making a mess because I am going to pull the carpet up when I am done and sand and refinish the hardwood floors. I would appreciate the help.
