Woolwax Pro Undercoating Gun by Kellsport

Good price and fucntions as it should for the most part. Only issue is there is no way to dial the pressure down so you would do yourself a favor to buy a variable pressure gauge to lower the psi for a more controlled spray. I sprayed cosmoline out of it with no issue. Seems to be well made

This gun is perfect! I used it to undercoat a 1999 Ford F-250 which has a decent amount of rust already on it. I also used it to totally coat a large dump trailer (except the bed) which has some surface rust. The gun and the wands worked flawlessly without a single issue. I was worried about the application due to some reviews I had read, but I had no problems. I used a 15 gallon, 3.7 cfm air compressor to apply. Again , somewhat worried it wasn’t big enough for the job, but it worked great! I gave it a few “cool down” breaks along the way.... The gun/wands sprayed consistently and evenly. The 360 wand was great for getting above muffler guards, inside of frame supports, inside rocker panels and for above the wheel wells. I also purchased the 5 gallon bucket of the NAS product used for undercoating because it was the best price per gallon. I transferred it to 10 one gallon plastic containers so I could easily shake it up and pour it into the containers which attach to the gun. Worked great. Keep the Fluid Film shaken up throughout the process. I recommend this product to everyone. Don’t go with a cheap sprayer.

Worked great. Came with three bottles. Very easy to clean.

Brief learning curve but works like a charm. Excellent.

Necessary addition for film.

Used to apply Fluid Film that was purchased more economically than through Amazon. Applied to 2 vehicles so far. Works very well. Used to preemptively prevent New Hampshire Seacoast rust on a 19 Silverado 1500 that I plan on keeping 20+ years. Hit Youtube and call Fluid Film if youre uncertain about how to do this. Fluid Films Customer Service is exceptionally helpful.

have sprayed 8 different undercarages and it takes about 1 hour to 1.5 to do a complete job. will be doing more in the future because all customers love it

Used with PB Blaster Surface Shield, product worked well to spray both the under carriage and inside the frame. Would have liked one more attachment for gun like a 30 degree extension, but overall worked good. If it holds up would recommend.

Used it once...so far so good, good spray angle and use the 360deg hose that you can attach to the gun.

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!!
