What grit sandpaper is typically used for initial filler shaping?

Explanation:
Shaping filler efficiently relies on a coarse grit to remove bulk material and establish the rough contour quickly. A grit in the 36–80 range cuts fast enough to skim off excess filler without creating deep gouges, which would take more work to fix later. After the filler is shaped, you switch to finer grits to refine the surface and prepare it for primer. Grits around 180–320 are used for smoothing after the bulk has been removed, not for initial shaping; 12–24 would be too aggressive and can gouge the surface; 400–600 is for finishing and feathering, not for removing large amounts of material. So, the best choice for initial filler shaping is a coarse grit in the 36–80 range.
