Product Description

FASTPLUS 2.75" x 15.75" – Hook & Loop Hand Sanding Block FB2

  • Ergonomic & Compact – 2.75" x 15.75" size fits comfortably in hand for reduced fatigue and precise sanding on edges, curves, and flat surfaces.
  • Fast Material Removal – Works with Fastplus sanding sheets or strips for efficient and accurate sanding.
  • Dust-Free Operation – Connects to a vacuum system via the included hose for cleaner, healthier work.
  • Easy Sheet Changes – Hook-and-loop backing ensures secure grip and quick, hassle-free sanding sheet swaps.
  • Durable & Versatile – ABS construction provides consistent pressure and long-lasting use; suitable for paint, putty, and plastics, perfect for both professionals and DIYers.

Who Is This For?

  • Auto body technicians leveling large flat panels — hoods, roofs, doors, and quarter panels
  • Collision repair professionals using guide coat technique to identify high and low spots
  • Woodworkers flattening wide boards, tabletops, and cabinet doors by hand
  • Anyone doing bodywork by hand who needs a rigid, long sanding platform for consistent panel flatness

For smaller detail areas and tight spaces, use the compact Hand Sanding Block 2.8"×7.8" instead.

Compatible Abrasives

Hook-and-loop surface accepts all FastPlus 2.75"-wide sanding strips and rolls:

Vacuum connection: Compatible with standard shop vacuum hoses for dust-free operation.

Grit Selection Guide

Grit Use Case Stage
80–120 Grit Initial panel leveling, guide coat reading Bare metal / filler shaping
150–180 Grit Panel flatness check and blend — most popular Filler to primer transition
240–320 Grit Primer leveling on large flat areas Primer / sealer
400 Grit Final hand sand before base coat Pre-paint finishing

Pro tip: Apply a thin guide coat (dark rattle-can spray) over the panel before longboard sanding — low spots stay dark, high spots sand off first, revealing exact panel shape. Use PuroFilm ceramic strips 80–180 Grit for best results.
