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

really like how it sprays would give it a 5 star if it had longer hoses for inner frame rail and a rigid straight wand with 90 degree tip

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.

I use this system every fall on my Wrangler and 4Runner. The set works really well for applying fluid film from the gallon container and allows the left over to be stored in the bottles between seasons. I used a “paint suit” and face shield from Harbor Freight when I was laying on my back for installation to protect myself from overspray. Although you may be able to find a less expensive version somewhere, I felt the combination of this kit was worth the price and will save my frame from premature rust due to winter salt. I recommend the product and would purchase again.

i purchased this after reading reviews about another spray gun at half the price. im glad I bought this one. This is a very sturdy unit and made to last!. I used this to apply Fluid film to two pick up trucks. I did not heat up the fluid film first so it took 110 psi of pressure to apply corectly but it came out well with a little over a quart for full coverage. The two extension wands are essential for getting inside frames and doors and they work great too. Time will tell as far as durability goes but judging on its build quality i have no reservations about it. I would not hesitate to recommend this to those looking for this type of spray gun.

As another reviewer wrote, “Stop reading this review and buy it!” I think the spray cans are fine for touchup, but this is by far the best alternative. If you have a compressor this is the only way to go it’s just so much better. After you get the gun adjusted to the amount of spray you want it’s pretty straightforward after that. I did wear a respirator because of the overspray in the air but it didn’t really get on the ground or anything else too much.

These guns are cheap! The product Fluid Film is great, upgrade the sprayers!

I used this with fluid film to undercoat my car for winter. It worked great and I had no isssues spraying for several hours. I would definitely recommend this product!

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 spray kit is awesome, minus a few things. I used it to undercoat a brand new 21 F150 with fluidfilm (very similar to woolwax) The sprayer is extremely well built, feels very solid. Using the brass spray nozzle you can get great coverage and it atomizes the product extremely well. The flow adjustability is great as well. However doing the inside of the frame is more difficult, and the flex wand doesnt help much. Within the first 5 minutes I kinked the hose as it is extremely stiff. Not a huge problem, as it keeps the product flowing, but just something to keep in mind. Then the 360 degree tip just fell out of it while I was spraying inside the frame. No idea where it is and I certainly wont be able to get it back. I recommend getting this sprayer, and finding a solid aftermarket flex wand to complete the package. Pros: - Great price -excellent build quality -includes multiple bottles -includes a spray nozzle as well as flex 360 degree attachment -great coverage -east to use and clean Cons: -Flex wand isnt very flexible at all -360 degree tip will fall off inside car frame -360 degree tip clogs easily
