What grit sandpaper is used for feathering?

Explanation:
Feathering means smoothing the edge of a repaired or sanded area so the transition into the surrounding surface is gradual and ready for paint or finish. The grit you choose should lightly abrade the edge without removing too much material or creating heavy scratches. Medium-fine grits around 100 to 120 provide the right balance. They remove burrs and shallowly break the edge, producing a soft, gradual transition that helps the new finish blend in. If you use a coarser grit, like 60 or 80, you’ll gouge and leave noticeable scratches that are hard to hide under paint. If you go too fine, like 150, you might not create enough feathering to blend the edge smoothly, leaving a visible line. So a 100/120 grit mix is commonly used for effective feathering.
