I'm removing all the wallpaper in my bathroom. (It's ugly as foo.) In doing so, I've scraped up the drywall a bit. Not any deep gouges, but enough to expose the brown paper under the primed part of the drywall. When I'm finished removing the paper I plan to prime with an oil-based primer, but prior to that what should I do to smooth out the wall? Is this a job for Capt'n Spackle?
