Woolwax Pro Undercoating Gun by Kellsport

Worked as it should

This sprayer works very well both with the spray nozzle and the two included tubes for small spaces. I placed the filled spray bottles in a utility sink filled with warm water for about 10 minutes before spraying. The amount of fluid sprayed depends upon how far the sprayer attachment is screwed into the gun. I found that fully seating the attachment then backing off two full turns sprayed the right amount of product for me. I was apprehensive about spending so much for an undercoating gun. But this gun/kit is well worth the money.

Works great! Thick oil needs to be heated up in hot water but once it’s thinned out it sprays amazing

I used to use spray cans of bar and chain oil, with 24 straws. They work for getting in the frame and hidden areas, but this gun is a much better way. It works faster and saves you money because you can use bulk oil, Fluid Film or chain&bar oil which are much cheaper. This gun gives a nice thin coating thats just enough to coat and protect, or thicker if you want. And when youre under there its not dripping all over the place. Heres a recipe: Get a gallon pail of fluid film then mix approx 50/50 in a jug with chainsaw bar & chain oil which is really sticky/tacky. Then mix in some used motor oil, bearing grease and Lucas oil stabilizer. Some people dissolve paraffin+kerosene into a cream and add that too. Im running the gun at 75 psi. The gun comes with a few empty bottles. The way this thing sprays, about 1 bottle will do half of a truck. The hoses are very good for pushing up into frame rails and over top of shock perches, etc . The hoses are not extremely flexible, which is a benefit when pushing them up into the frame. Only thing is, they wont turn anything other than a very gradual curve...sometimes that doesnt work if the frame hole is small and you cant make the turn thru that hole. I wish they provided another hose that is thinner, like 1/4 O.D. so that you could get in smaller holes or smaller places. For these few problem spots I revert back to spray cans and LONG straws. An excellent thing to buy along with this gun is the ShopStraw FS250 . You can cut this straw into a 2 ft section and put it on spray cans of Fluid Film or Johnsens bar and chain oil JON4602 case or 4723 can , or any cheap spray chain/bar oil . You can see all this in my pic . Yeah this gun is a hundred bucks but If you think long run, your frame rusting out usually results in junking the vehicle or spending alot of money and time. A hundred bucks is nothing to prevent your frame and body from rusting out. If youre on the fence, let me save you the time. Just spend the damn money, get this gun. Get a jug of cheap Bar&Chain oil, Fluid Film and used oil. Some nice jack stands also make the job easier. I use Big Red jack stands, they are reasonably priced and are DOUBLE LOCKING. Now go and protect your baby from road salt and rust.

This kit exceeded my expectations. I set my air to 85#, then this gun made it easy and controllable to apply fluid film under my truck and trailer. The wand was very helpful at reaching those tough to get spots. The 360 degree wand made it capable to reach inside the frame of my truck. I would recommend this and would buy it again if needed. Thanks

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 worked absolutely Perfect for spraying fluid film undercoating. I’ll be using this gun every year to undercoat my vehicle so hopefully it keeps working great.

Works better with the brass tip. The wand attachment is nice for reaching into tight spaces, but it limits the flow of undercoating. Works well!

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

bought this to use with my fluid film and it works wonderfully. i set my compressor to 80psi and it sprays well. you do have to unscrew the end to get the spray to come out. the hoses work well to get into the doors, frames, and other crevices the multi way hose works best for the frame and the straight hose works best for the hard to reach spots. whe additional bottles are nice to fill and use after you are dont with the first one. and the casps are nice to store any additional remaining product.
