What grit for sanding caps?

The grit of the sandpaper determines the fineness of the sanding. Coarse sandpaper, like 40-80 grit, is ideal for removing large imperfections, while medium sandpaper, like 120-220 grit, is perfect for smoothing surfaces. Fine sandpaper, from 320 grit and higher, is used for the final finishing to create a smooth, paint-ready surface. Choose the grit that best fits your project for optimal results!
