Woolwax Pro Undercoating Gun by Kellsport

Have sprayed several gallons of krown with it. Gun is high quality and sprays better than expected.

Great Product!

used it to spray rust sealer and it worked great

Works great for undercoating cars.

Spray gun works as it should.Only improvement I would like to see is a different way to adjust the pattern.To max out product being sprayed,it requires hose to be barely threaded on which results in working loose while moving hose around spraying.Other than that,it works great.

Bought this to use to undercoat my 2019 4runner with Fluid Film. It works great, very impressed. Im doing the job with a 6 gallon compressor too, no issues. My initial rookie mistake of twisting cap all the way at tip cost me some time. But once I figured how to use it, its smooth sailing. Really like the hose attachments too. I recommend the gun, have now done two vehicles with no issues.

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 used Woolwaxs undercoating gun to undercoat my F250. It does a good job. It sprays predictably at least once you figure out the nozzle. I was running about 90 psi through it, and it ran fine. The nozzle seems to be where youll have issues. Getting it adjusted and keeping it adjusted takes a little practice. If its not spraying for you, thats where Id start. While I appreciate the two flexible extensions, I wish it came with a rigid wand so that I could have gotten at some tighter spaces, otherwise Im very happy with the gun. Once complete with the job, I wiped down the sprayer head, let the feed tube drain itself into a bottle, then ziplock bagged it in anticipation of future use.

Great set up. Make sure you use an air fitting with female thread if you remove nipple and try to thread a more standard fitting with male thread you will crack the grip and it will leak air. Yes i still gave it a good review even tho i broke it. Purely my falt i should have gotten the correct fitting.

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!
