How It Works

The FLEX L3403 is a lightweight rotary polisher designed for high performance and fast polishing work. The L3403 was designed and built for OEM automotive builders, body shop technicians, professional detailers, and weekend warrior enthusiasts. Use the FLEX L3403 to polish paintwork, remove scratches, swirls, heavy water spots, and restore pure reflection with optical clarity. Old rotary machine designs were clumsy and heavy, and they were originally designed to polish marble and granite slabs. The FLEX L3403 is compact, ergonomic, lightweight, and balanced to deliver fantastic polishing results with minimal effort. Older heavy machines put excess pressure on painted surfaces, generate excess heat, and cause unsightly holograms and marring. The FLEX L3403 weighs less than 5 lbs, and exerts the perfect amount of pressure to polish any automotive paint finish to perfection. The ergonomic industry-standard design fits comfortably in the hands and follows any vehicle contour for perfect polishing results. Switch out the included low-profile 5 inch TORQ R5 backing plate with any industry-standard rotary backing plate to tackle any job. Use 3’’ backing plates for small polishing pads to polish small areas or headlights. Switch all the way out to 1 inch backing plates to polish small vents and louvers with laser accuracy. The FLEX L3403 is the professional’s choice for polishing any automotive surface quickly, comfortably, and easily.

Professional Rotary Polishing Results

Rotary polishers are the professional’s secret weapon. A skilled detailer can effectively erase swirls and scratches from paintwork with a rotary polisher in seconds. Polishing and paint correction is a process that gently removes the topmost “dead” layers of paint to reveal the shiny, lustrous, untouched paint underneath. Abrasive compounds rub on the surface to “cut” underneath swirls, scratches, oxidation, water spots, chemical etching, and other defects that mar the finish. Finer polishes and softer pads refine the finish to restore luster, depth, and clarity to the reflection. The FLEX L3403 is a professional grade machine built for years of use in any professional body shop, or enthusiast garage. Professionals choose the FLEX L3403 because of its powerful paint correction capabilities and lightweight design. Detailers polish paint with the L3403 to remove swirl marks and scratches, restore gloss and color, and rejuvenate luster. More advanced users switch out the backing plate to take on smaller painted areas like grilles and door jambs, polish and restore headlights, repair dashboard wood trim, and even scrub stubborn carpet stains. The FLEX L3403 is the detailer’s choice for powerful and smooth rotary polisher applications.

Precise And Smooth German Design

FLEX tools are conceived of and designed in Germany. FLEX crafted this industrial heritage into a smooth and quiet machine. The FLEX L3403 uses helical cut gears and smooth variable power controls for precise, smooth, and quiet action. FLEX Tools designed the L3403 with advanced tachometer speed controls, soft startup spin, pressure-sensitive accelerator trigger switch, power interruption restart protection, overload protection, temperature monitoring, and infinite speed selection gearing. The speed control knob features six distinct speed settings with infinite adjustment between each one. The L3403 can be tuned to spin at the perfect speed for any polishing job. The industry-standard form factor is ambidextrous and fits perfectly in the hand for any left handed or right handed detailer. The threaded output shaft is a universal thread that accepts any rotary polisher backing plate for machines sold in North America. Use any sized backing plate from 6.5’’ down to 1’’ for ultimate detailing versatility on any job. Use the FLEX L3403 to polish paintwork, headlights, metal trim, door jambs, wheels, tail lights, optical plastic, glass, and more. The FLEX L3403 is the smooth rotary polisher for any detailing professional or enthusiast.

Intuitive Variable Trigger Controls

The FLEX L3403 Rotary Polisher delivers unmatched power and control with a convenient and intuitive variable speed trigger. At full trigger squeeze, the machine spins at the maximum rated output of the speed setting selected. FLEX designers also incorporated a convenient lock button to hold the trigger for reduced fatigue during longer polishing sessions. However, unlike other rotary polishers, easing off the trigger slows down the buffer. This unique feature gives detailers more control by tailoring the perfect amount of machine power for smaller, more contoured, or sensitive areas. Use a full trigger squeeze for full power at any given speed setting, or adjust trigger pressure for precise control with less power or slower startups. Every paint job is different, and every polishing session must be adjusted to suit the particular car. Professional detailers and hardcore enthusiasts need the flexibility to adjust for perfect results on any vehicle. Choose the FLEX L3403 Rotary Polisher for extended polishing techniques with more (or less) power than a standard rotary polisher machine.

Lightweight And Versatile Form Factor

Detailing and body shop professionals prefer the rotary polisher for its fast action and one step results. Rotary polishers easily remove wet sand marks, heavy swirls and scratches, and oxidation to restore gloss and optical clarity to painted finishes. The FLEX L3403 Rotary Polisher is the fine rotary tool for any professional or hardcore enthusiast who wants a lightweight and easy-to-use machine. Traditional rotary polishers are large and heavy machines designed for polishing slabs of marble and granite. Wielding one of these cumbersome machines around delicate automotive paintwork is a self-defeating act that always results in unsightly holograms and poor polishing results. The FLEX L3403 uses advanced German micro-motor and gearing technology for professional polishing power in a compact and lightweight package. The L3403 fits in the hands and maneuvers around automotive curves and contours with a light touch that is safer for sensitive finishes. The FLEX L3403 is the perfect rotary machine for professional results with minimal strain.

Durable TORQ R5 Rotary Backing Plate Included

The FLEX L3403 comes equipped with the TORQ R5 rotary backing plate. This low-profile backing plate uses flexible materials that contour to curves for superior polishing results on any vehicle. The low-cut profile helps fit any polisher into tight areas underneath side-view mirrors, roof racks, vents, grilles, louvers, spoilers, diffusers, and more. TORQ backing plates use hook and loop to grip buffing pads with a solid connection that removes easily by hand for fast changes. The TORQ R5 backing plate installs in seconds: simply lock the buffer head output shaft with the stopper button, then screw the backing plate onto the machine. The TORQ R5 backing plate uses a universal thread to fit any rotary polisher sold in North America. Simply attach it to turn any rotary polisher into a versatile buffing machine for any vehicle.
