Overview
The 303 Marine Quick Wax is a spray-on protective wax designed to quickly enhance shine and add surface protection between full detailing jobs. It’s formulated with natural Carnauba wax, offering a glossy finish while helping to repel water spots, light dirt, and UV damage. This makes it ideal for maintaining the exterior surfaces of boats, RVs, and other vehicles that are regularly exposed to sun and weather.
While originally formulated for marine use, its easy application and UV protection benefits also make it useful for RV gelcoat, painted metal, and other non-porous exterior surfaces.

Inspector’s Note (RV Pro Solutions Insight)
As an RV exterior detail enhancer, this quick wax is superb for touch-up shine and added UV defense between deeper wax applications. It’s not a replacement for full protective sealing but is extremely handy when you need that freshly detailed look before a trip or event.
