Details: Fluid Film Pro Undercoating Gun * modified internally to apply Fluid Film NAS undercoating * adjustable nozzle for best flow * includes (3) clear quart bottles and brush cap * includes 24 open-end flexible wand * includes 18 360° flexible extension wand * Made in Europe Note: The company that has made these guns for many years, Kellsport Products has switched from the Fluid Film label on the bottles, to a Wool Wax label. The guns with the Wool wax labels are the newest inventory from the manufacturer. These guns are designed specifically for Fluid Film and Wool wax Undercoating. Note: The 32 wand with the 360° nozzle generally works well with Fluid Film because it is a thinner formulation. Wool wax is a much thicker formulation and more resistant to wash-off. When using the Pro Gun with Wool wax it is necessary to shorten the 32 wand down to 18 for best results.
