woolwax Pro Undercoating Gun by Kellsport;

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 "WoolWax" label. The guns with the "Woolwax" labels are the newest inventory from the manufacturer. These guns are designed specifically for Fluid Film and Woolwax Undercoating. Note: The 32" wand with the 360° nozzle generally works well with Fluid Film because it is a thinner formulation. Woolwax is a much thicker formulation and more resistant to wash-off. When using the Pro Gun with Woolwax it is necessary to shorten the 32" wand down to 18" for best results.
