Buying Guide

Block flexibility and shape

Choose foam or contoured blocks that compress and wrap around curves to maintain even pressure and avoid gouging on rounded surfaces

Abrasive attachment system

Select blocks compatible with PSA or hook-and-loop sandpaper for quick sheet changes and secure hold on curved sanding pads

Grit selection and rolls

Look for sets that include common grits or offer abrasive rolls (e.g., 120-grit rolls) so you can cut custom shapes and match grit to material and stage of finish

Set composition and value

Evaluate kits that bundle multiple blocks and sheets to cover auto-body, woodworking, and general hand-sanding tasks for better per-piece value
