Woolwax Pro Undercoating Gun by Kellsport

Dont waste $50 on a cheaper model. This is the best of the best for sprayers. Inner cavity wand and spray extensions are good! Little bit of a messy job but I work under jackstands. Blaster surface shield is what I used and product flow was awesome!

Works great....the spray nozzles alow complete coverage. A must have.

Spent the extra money and got the pro gun kit. Did an amazing job on my 2015 Ram 2500 Megacab. Sprays a nice fine mist and maybe used a half gallon on this large of a truck!

At first the gun would not spray at all! Lots of air coming through but no fluid film! I almost gave up and returned as defective! Then bam! Adjust the nozzle to not tighten all the way and it started shooting! This needs to be on the faq because I’m sure im not the only one. As for functionality, gun shoots great! However, the spray wand was kind of weak and not as effective like a few other reviewers have mentioned—might need a stronger psi for that. I was using around 70psi. It’s pricy for what it does. Otherwise, great product!

Works as described with wool wax

I used this to spray Fluid Film and treat a pickup truck. Worked well. The supplied multiple bottles are helpful as you pre-fill them and then spray without interruption.

My husband use this to spray in under coating on his trailer. Everything worked fine.

I like that you can adjust the pattern. I sprayed my truck on a colder day , high 30’s , so I had the extra jar warming up inside. Very happy with it. Sprayed inside frame and all under body and some in engine bay

Easy to use, clean and store. Worked very well applying Blaster Surface Shield at 50 PSI.

I love the gun you can set to put out as much as you want.plus the hoses are good for taking plastic plug out and putt hoses in and spray.
