What type of primer fills small scratches and imperfections?

Explanation:
Primer surfacer is used to fill small scratches and imperfections and to create a smooth, flat surface for the base coat. It has higher solids and filler content, so it can level out minor defects and hide tiny flaws, reducing how much sanding is needed before color is applied. After it cures, you typically sand it with a medium grit (around 400–600) to achieve a uniform finish ready for the basecoat. Other primers have different roles: etching primer prepares bare metal for adhesion, sealer creates a barrier to prevent bleed-through and even out color under the topcoat, and primer sealant mainly acts as a protective barrier rather than a filler for surface imperfections.
