Woolwax Pro Undercoating Gun by Kellsport

The best wool wax applicator since... well driving through a herd of sheep i guess.

Fluid film is never easy to clean but the product is great quality. Takes some getting used to adjusting the nozzles but once dialed in, works great. There are cheaper models that also work great but this model includes the extensions and more control ability.

I was surprised that it worked so well with a cheap 4 gallon 125 psi pancake compressor. I did heat the fluid film up and got it flowing easily. I put the gun on the end of a 50 flexzilla 3/8 hose and was able to do the job on jack stands in the garage.

I use blaster surface sheild to undercoat my vehicles and this gun is perfect for spraying it has a great 360° nozzle for inside frame rails and other hard to get places Ive done both my trucks and another car and havent had any issues I would highly recommend this gun for spraying any undercoat

Spend a little extra and you won’t regret it. This works awesomely with the thick Fluid Film rust protection product without thinning it. It’s worth the money!

Looks good although I havent used it yet. I think its a bit pricey.

Works as described with wool wax

After 35 years in the Auto Body business, I know a quality tool when I see it. This is made in Italy and has a couple adjustments for air and fluid just like on a good spray gun. Its true, you get what you pay for.... this wasnt exactly cheap, but cheap rarely works or lasts for years. It comes with several wands to reach inside doors, fenders, and unibody and frame rails. Its a great purchase and works awesome. Im sure Ill have it another 30 years!.... If Im still around that long ! I would defiantly recommend this gun to others.

I ordered this product as part of a kit with 3 spare jars for use on undercoating my 2012 Silverado. I ordered a gallon of product. I live in Iowa, so salt spray is a big problem here with vehicles rusting. I used this gun and the long plastic wand to spray Fluid Film in every body cavity I could find. I sprayed it extra heavy in areas where most pickups rust (areas above wheel wells, inside rocker panels, inside body cross members, exposed areas underneath, back of metal bumpers, etc. The gun worked well, I just used a small pancake sized compressor with a output regulator set at about 50 PSI. That sized compressor kept up fine. The material isnt really going to atomize like a normal spray gun(think snot consistency), but it does come out in a fairly uniform spray worth 4.4 stars. I doubt you could get a five star performance from the material being sprayed with a low pressure gun like this, but it definitely gets the job done and done quickly and easily. Worked good no matter what angle I held it at as I reached different areas. I highly recommend ordering the kit with the long 32 wand, as that is how I did all of the enclosed areas. Careful if you have door mounted speakers, as the stuff might jack them up. As for the Fluid Film product itself, I have also put it on by the supplied brush cap to the moving parts of my 3 point tractor attachments, which live outside year round. I lubed several items with it like the 48 snow blower chain, the 3 point hitch moving parts, the hitch pins, etc. Things definitely move nicely now. Time will tell how well the Fluid Film protects things. If I were Fluid Film, Id spray the right side of a vehicle and do nothing the the left side and do a video shoot after say ten years in the salt and slush. I do wonder about salt mixing with the product since it stays a liquid that clings to the surface. I plan to keep applying it either until I prove it does or doesnt help against rust. Sure seems to make sense, coat the steel in oily slime and how could it rust? I also did a test with a piece of hot rolled angle iron coated in the product. I put it outside where snow collects next to an untreated piece from the same piece of angle iron. Well see how long the treated part resists rust. I will try to report back.

This was exactly what I needed. I’ll need to buy a bigger air compressor my 1.5 HP, 6 gallon compressor just wasn’t big enough to hold air. I’d need to constantly wait and let the PSI build to At-least 120 for the oil to spray out nicely. But this spray gun and the items that came along with it were just amazing. Thanks!!
