Variable Speed Power Sander / Polisher Greenlight Variable Speed Surfboard Sander / Polisher Built for surfboard builders, glassers, and repair work, the Greenlight Variable Speed Sander / Polisher gives you the control needed for every stage of surfboard finishing — from lap and fin box grinding to seal coat sanding to final swirl-free polish work. Designed for Surfboard Sanding & Polishing Unlike fixed-speed polishers that run too fast for delicate surfboard work, this variable speed unit allows you to dial in the correct RPM (1300 - 3500RPM) for each stage of board building. Proper speed control helps: Prevent resin burn-through Reduce heat buildup Improve sanding consistency Minimize swirl marks Extend pad life Improve polish quality Maintain better control on rails and contours The result is a cleaner finish with less risk of damaging your glass job. Features Variable speed control for sanding and polishing Standard 5/8"-11 arbor spindle Compatible with: 7" Hook & Loop Polishing Backing Pad (included) Flexpad Surfboard Sanding Pads 120 Volt standard household plug Removable side handle Mounts left or right side for left-handed or right-handed users Ergonomic grip for extended sanding sessions Heavy-duty motor designed for surfboard shaping environments 1-Year Limited Warranty Recommended Speeds for Surfboard Work Correct speed selection is critical in surfboard glassing and finishing. Running too fast creates excess heat, clogs abrasives faster, and increases the chance of sanding through laps or burning resin. Lap Grinding Use a medium speed setting. Enough RPM to cut efficiently Lower heat buildup near rail laps Better control around curves and transitions Higher speeds can quickly overheat resin and dig into laps. Hot Coat Sanding Use low to medium speeds. Helps keep the board cooler Produces more even scratch patterns Reduces chatter and gouging Improves control on flats and rails Variable speed becomes especially important with finer grits where excessive speed can load paper and create uneven finishes. Fin Box Grinding Use lower speeds with caution. Fin boxes concentrate heat quickly. High RPM can soften surrounding resin or damage foam near the install area. Lower speed settings provide: Better precision Reduced melting Less risk of overcutting around boxes Compounding Use medium speeds. Compounds need enough speed to activate properly without overheating the resin surface. Proper variable speed control helps: Improve gloss clarity Prevent compound sling Keep compound temperatures under control Final Polishing Use lower to medium polishing speeds. Too much RPM during polishing can: Burn the polish Create swirl marks Distort gloss finishes Overheat dark pigments and tints Controlled lower speeds produce a cleaner, deeper gloss finish. Proper Use & Care Surfboard sanding creates extremely fine resin and fiberglass dust. Proper maintenance is critical to extending motor life. Important Maintenance Notes Blow out the motor air vents after every use using compressed air Resin and fiberglass dust buildup inside the motor can cause overheating and eventual electrical failure Keep ventilation ports clean and unobstructed Do not store the tool with dust packed into vents Always allow the tool to come to a full stop before setting it down Compatible Accessories 7" Hook & Loop Polishing Backing Pad (included) Flexpad Surfboard Sanding Pads Wool polishing pads Foam finishing pads Show more
