This is the Woolwax® PRO applicator. We consider this to be the best applicator available for Woolwax® undercoating applications. We had this applicator modified and developed specifically for Woolwax® undercoating. This 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 applicators 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 Applicator.

Our Undercoat applicators 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 tool 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.

Woolwax offers a lot of different undercoating spray applicators, and we realize that it can be confusing. Please see the link below for our Undercoating Spray Applicator Guide

Good spray gun!

As my first time applying a product such as Woolwax, i went for the spray gun that had some decent options and accessories. This one in particular looked like it would work well and I feel that it performed just right. I was even able to apply the Woolwax black product on a 50* day without any issues. I'm looking forward to spraying the rest of my cars.

Customer review

About 1 month ago I purchased the pro series spray gun, PSI regulator and 2 wand set to spray Woolwax black on my vehicles. When I received the items there was no male nipple hose adapter provided. Buyers be aware out of the box it is not plug and play. After installing the hose adapter I found the spray gun worked as described in 50 degree climate. A day later I attempted to spray in 25 degree weather and had issues with the Woolwax solution thickening. Once the solution began solidifying the spray thickness became inconsistent and blotchy. When in warmer weather I found the air regulator accessory a good purchase. The regulator helped eliminate overspray and provided a consistent spray thickness. My vehicles now look like they were professionally sprayed. My only gripe is that the 24 inch wand broke within 15 minutes of me using it. The hose popped off the “tail end” and would not hold a seal after reconnecting it. I resolved the issue by cutting the wand shorter and reconnected the tail end, which then held its seal. Overall I am happy with the purchase.

Did it myself

I had done my homework and found that Woolwax is one of the top undercoating products on the market so I began looking for a contractor to do our 3 vehicles,I could not as all local contractors were booked atleast 6 months out so I ordered the Progun and 3 gal of the black undercoating and did them all myself,easy to spray and control gun with the wands,able to hit those hard to reach places and superior coverage,it also looks great,I taped off areas I did'nt want touched,It was in the 40's when I sprayed so I warmed my undercoating by sitting it in front of the fireplace prior.Great product and quality.

Great applicator

Worked perfect for the DIY specialist. Wish the supplied extensions were a little smaller diameter to reach the hard to get too, small access points in the rear fenders. Other than that.. worked flawlessly.

Very happy with this product. First purchased a different sprayer and it only lasted an hour. Can stripped out and trigger bent to side. When I received this one I sprayed a gallon and didn’t have any problems. 5 stars so far.

Ideal for undercoating

This pro gun makes undercoating a piece of cake. The gun itself works exceptionally well and is light, but solid, and easy to use. On and off the trigger results in immediate bursts of spray. The bottles are great and it's always good to have a few handy so when you're under the vehicle and run out, you can have more ready to thread on. The wands work really good and make it easy to coat the inside of the frame with the 360 tip. Even the straight through wand is really handy when you want or need a less atomized spray. The wands are sturdy but pretty flexible. Just be sure not to over bend (kink) them or the pressure vent on the gun will burp its contents. Easy to avoid this though. The only enhancement I'd love to see is a quick release option for the wands. I know the pressure pot version has them but I'd love to see it added to the pro setup.

Fantastic customer service and a pleasure to deal with. Sprayer functions great, and being able to purchase replacement parts is a massive positive. I'd recommend purchasing the regulator through woolwax as well to easily set the pressure to the gun.

Pro Sprayer

This is my first experience undercoating, but it seemed easy enough so I jumped in. I’m very happy with the quality of the sprayer. I warm the bottles of Wool Wax in hot water before I spray to thin them out a little. I have no issue spraying inside my heated garage all winter long. The product doesn’t drip and only goes where you spray it, so the mess is very minimal.

A Must buy

Don’t have anything to compare this with but I’m happy. I have a harbor freight 29 gallon Air Compressor. I used this sprayer on a 50 degree day running 90 Psi and had no issues. The Gun appears to be High quality and I chose this over the cheaper ones as seen on Amazon. You know what they say Buy once Cry once, Do it right the first time.

I purchased the pro gun kit to spray my Jeep. I wanted to do the job myself since I do all of the work on my Jeep. I was very impressed with the quality and the price and also the ease of operation. I called customer service about the way to clean the gun and was pleased with how I was taken care of.

Great Quality

I bought the PRO gun because I'm kinda tired of buying cheap Asian products, and although I don't plan on using this frequently, I do expect to be using it for the next 20 years. The quality does appear to be inline with the price. I'm not familiar with spray guns, so this may be obvious to some. There is a hole on the top of the portion of the gun that the undercoating containers thread into, so if the gun is tilted at an extreme angle or tipped on it side for too long there will be a mess of WW flowing out from the hole. Not a big deal, just not noted anywhere that I'm aware of.

Great sprayer, you can buy everything you need to DIY

Sprayer works great for both thick and thin lanolin under coatings, plus you can buy extra attachments or replace worn hoses easily. This kit will give you the best bang for your buck.
