This is the Woolwax® PRO applicator gun . We consider this to be the best applicator spray gun available for Woolwax® undercoating applications. We had this gun modified and developed specifically for Woolwax® undercoating. This gun comes complete with (1) 18" flexible wand with 360° nozzle, and a 24" flexible wand.
Our Undercoat guns do not need to be cleaned after use when using with Woolwax®. Woolwax® undercoating is solvent free, so there is no evaporation or hardening process. The Woolwax® left in the bottle will thicken over time. But you can restore to its original viscosity by shaking vigorously.
Some people do prefer to clean the gun and wands. To do this we recommend just putting some solvent (acetone, mineral spirits, paint thinner, etc.) into one of the bottles and spraying a bit through the gun. Some people just put water and dish washing liquid into the bottle, and spray it through. They say that it works fine.
Most people just leave the gun loaded and ready to go without doing anything at all. That way you can do a quick touch-up or spray some outdoor power equipment with almost no setup time.
Bottom line……. Don’t worry about the undercoat guns when using Woolwax®. They won’t clog.
