This gun was developed to spray Fluid Film® & Woolwax®.  This applicator gun used by many of our professional applicator locations. We consider this to be the best applicator spray gun available for Fluid Film® & Woolwax® undercoating applications. We had this gun modified and developed specifically for woolgrease undercoating. This gun comes complete with (1) 32" flexible 360° wand &  (1)  24" straight open end wand.

  • Modified internally to apply Fluid Film® or Woolwax®
  • Adjustable nozzle for flow control
  • Includes (3) clear quart bottles with caps
  • Includes 24"" flexible open-end wand
  • Includes 32" flex 360° extension wand
  • Includes brush applicator
  • European Made
Note:  We include a long 32" 360° with the Pro Gun Kit. This 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. 

Air Compressors for Undercoating guns

We get this question all the time.
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 n
o 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.

Pro Spray Gun kit
Nice sprayer. PROS: all metal (containers obviously plastic for easy viewing of fluid level); Brass tip; Made in Italy; adjustable flow rate; stiff but flexible nylon extensions with brass fittings; one extension has 360 deg application; multiple containers for easy preloading of FF; one cap has brush attached; gun does not need to be cleaned after use so you can grab it and use it even for small projects; add'l accessories available. super-fast shipping. CONS: pricey; no option to change spray pattern; unable to produce a fan spray. ---- Overall, applies product evenly and makes your uncarriage look sharp.

Works Great
This gun works excellent. My son used it to spray his Jeep and Dodge truck. Spray pattern is right, easy to use, wands work well inside frame. Well worth the cost. Only difficult part is getting the product from the gallon to the spray bottles. next time I will buy the gallon lid pourer. otherwise, use a funnel and be patient. Oh, and dont spray up to your door handles. You will end up with it all over your clothes when you get in and out of the vehicle! Ask my son! :)
