This polisher comes with a 6" interchangeable backplate that fits 6-6.25" pads with hook & loop (velcro) backings. The backing plate can be replaced with a 5" model (sold separately) for smaller surface areas.

Yes. 6" backing plates offer faster coverage on large hulls and decks, better pad stability on flat and mildly contoured surfaces and improved efficiency when paired with long-throw motion. Professionals may still keep a 5" setup for tight areas, but for boat correction, 6" on a 21mm throw is considered gold standard.

Gelcoat is significantly harder than automotive clear coat, which means it loads pads heavily and demands sustained torque. A 1000W motor ensures the machine maintains orbit and pad rotation under pressure, especially important when correcting oxidation on large hull surfaces.

In many cases, yes, and with fewer risks. Our 21mm DA polisher paired with our pads and oxidation remover compound can remove heavy oxidation, level gelcoat effectively and finish down cleaner and smoother than a rotary. Rotaries still have a place for extreme cases, but for most DIY boat owner in particular, a long-throw DA delivers near-rotary results with dramatically less learning curve.

Absolutely. Our best-in-class materials and craftsmanship, 1000W long-throw DA is engineered for extended run times, consistent torque under load, reduced operator fatigue and reliable performance in marine environments. You will find it rivals legacy brands 2-3X its price point and stands out among competing tools in its tier for overall, no-nonsense build quality, substantiality, fit and finish. For professionals, it means fewer passes, faster jobs, and consistent results, all for a better price. For DIY boat owners, it means professional outcomes without taking on professional risk.
