Diamond Fusion™ Exterior Glass Protection

Glass looks smooth to the naked eye, but under a microscope every windscreen is covered in tiny pores and imperfections that trap water, mineral deposits, road film and the fine grit that eventually turns into pitting and stone chips. Motorhomes and RVs spend hours on the open road in exactly the conditions that accelerate this — highway grime, driving rain, oncoming headlight glare and the odd flick of gravel from a passing truck. Over time it all takes a toll on visibility, and clear driving is safe driving.

Diamond Fusion™ is a professional-grade nano-coating designed to bond with the surface of your glass and fill those microscopic pores. Once cured, it forms an ultra-smooth hydrophobic layer that causes water to bead up and roll straight off the windscreen, dramatically improves visibility in rain, reduces scatter from oncoming headlights at night, and adds a genuine layer of impact resistance that helps prevent chips, cracks and long-term pitting from road debris.

We apply Diamond Fusion™ in a controlled indoor environment at our Mount Wellington workshop, starting with a full glass decontamination and polish so the coating bonds to a properly prepared surface. It's backed by a manufacturer warranty and is one of the most cost-effective safety upgrades you can make to a motorhome — especially for owners who cover long distances, travel at night, or spend a lot of time in coastal and mixed New Zealand weather.
