After installing a pre-hung steel door, I found that the interior wall bows out past the door frame. At the highest spot, about halfway down the wall, the drywall bows out about 3/8"" past the frame. How should I install the moulding around the door frame? Should I try to shave down the wall or build up the edge of the door frame in that area with some kind of filler to bring it level with the drywall?
