Use a caulk gun to apply a continuous bead of paintable caulk along all seams where the installed molding meets the wall or built-in unit. Smooth the caulk with a wet finger or a caulking tool to create a clean, seamless transition. Then, apply wood filler to all visible nail holes, pressing it firmly into the holes to fill them completely. Allow both the caulk and wood filler to dry thoroughly according to their respective manufacturer's instructions.
