Flexible and rigid hand sanding blocks for automotive panel work. SPX sanding blocks conform to body contours for consistent sanding pressure and professional results on filler, primer, and topcoats — trusted by panel beaters and spray painters across Australia.
Decision shortcuts
A quality sanding block is one of the most important hand tools in any panel shop. It distributes sanding pressure evenly across the abrasive, preventing finger grooves and high/low spots that would telegraph through primer and paint.
Types of sanding blocks:
**Rigid blocks:** Flat, firm blocks for levelling body filler, sanding flat panels, and feather-edging. The rigid backing ensures you sand flat rather than following surface undulations.
**Flexible blocks:** Slightly compliant blocks that conform to gentle curves — ideal for door panels, bonnets, and moderate contour work while still providing more pressure distribution than hand sanding alone.
**Contour blocks:** Shaped blocks with curved profiles for sanding body lines, radius edges, and tight contours where flat blocks would cause uneven contact.
Choosing the right block:
Most SPX sanding blocks accept standard 70mm wide abrasive rolls or can be used with sheet abrasive cut to size.
