To paint or not to paint the underside
You can smooth over your rough undercoating with 36 grit on a DA sander. Patch in and texture missing undercoating areas with Duroglas waterproof body filler.
Then you can repaint the whole underbody of the car, undercoating and all. Nothing wrong with leaving the undercoating on there, will look factory when done properly.
