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.

  • Modified internally to apply Woolwax® undercoat
  • Adjustable nozzle for flow control
  • Includes (3) clear quart bottles with caps
  • Includes 24" flexible open-end wand
  • Includes 18" flexible 360° extension wand
  • European Made. Modified & Assembled in USA
Note:  The 32" 360°  optional long wand may not work well depending on the temperature, compressor psi, and product viscosity.  This long wand can easily be shortened by removing the barbed fitting at the end, cutting the tube, and replacing the barbed fitting. Because Woolwax® is thicker than any other undercoat product, we find the ideal length to be about 18". At 18" it works perfectly with Woolwax®.  Other thinner products may work well with a longer length.

Kellsport Products undercoating guns use very little pressure. Only 70-90psi. Most compressors run around 125 psi. So the psi and the cfm are not really important in this application. The tank size is important. We recommend no smaller than a 3 gallon tank size. Any smaller than that and you are constantly waiting for the tank to recover. Most very small compressors will say on the box "not adequate for spray painting". As long as you can spray paint with a compressor, you can use it to undercoat. Many people have told us they they have bought inexpensive compressors ($75+/-) from Harbor Freight or similar stores and they work just fine.
We suggest putting an inexpensive regulator ($10+/-) on the gun end so you can tweak it from the gun without having to go back and forth to the compressor. Don't try to remove the fitting at the bottom of the gun handle, as it does not come off. It's a standard 1/4" fitting. bring the gun with you to the store for the right connection.

Cleaning the Undercoat gun.

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.
