Woolwax Pro Undercoating Gun by Kellsport

Works great for undercoating cars.

Works as described with wool wax

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!

I have undercoated about 15 cars and trucks using fluid film with this sprayer. My only complaint is that the plastic hoses tend to kink easily, but they can easily be replaced with hose of the same ID at a hardware store. Ive sprayed fluid film with a few other sprayers and this one is the easiest by far.

works great

Stop scrolling. This is the sign that youve been looking for. This kit pays for itself in application speed and quality. Hooked this up to a 100psi compressor with a regulator at the sprayer for quick adjustments. Go to you local hardware store and pick one up. This sprayed cold and hot fluid film extremely well, much better and cheaper than the aerosol cans!! Hit all metal surfaces excluding brake calipers / rotors.

Sprays great, good pattern. Tips all work well. I used an 80 gallon compressor at 120 PSI and it sprayed perfect.

Loved the product worked great with fluid film black bought a different one for 50 dollars and it had no suction defiantly recommend this one.

Forget the cans if youre thinking about undercoating, this gun makes it quick work with MUCH less mess from the adjustable nozzles. 80-100 psi from a 2.5gallon compressor worked just fine with 3-5 second bursts. Took off a star because for the price a QD or two would have been nice. Do yourself a favor and get a right-angle connector so it will sit flush on the ground more easily. The 360 nozzle works fairly well, but youll want to make your first pass with the straight nozzle.

Nothing to dislike about the product. I have been having difficulty pushing fluid film and found that the gun does as advertised. That is refreshing. Looking forward to trying it on linseed oil for my wood preservative.
