Woolwax Pro Undercoating Gun by Kellsport

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.

Used this spray gun with Fluid Film and it works great. Set the compressor air pressure to 80 psi with good results. Be careful not to kink the spray tubes as the gun relief valve will spill over creating a mess! The plastic spray tubes are stiff and kink easily so you need extra space to work to avoid that. Tubes fit into most areas of the frame and body of vehicles. Already did three vehicles and it works very well!

A very good quality sprayer suitable for car undercoating.

With what vehicles cost, why wouldnt you care for the underside (Frame, etc..). I had been doing my vehicles with rattle can the last couple of years and the undercarriages still look great. This has made that job much easier, and far more precise. The attachments allow me to get to the hard to reach areas and inside the various cavities with ease. I knocked out two of my vehicles today in under two hours and cleanup (depends on what material you spray) was easy....

used as an undercoating treatment , to prevent winter rusting have not applied yet

Sprays nice. Easy to use. Makes job so much easier. I used wool wax. Great investment.

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

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.

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!

Still reading? You shouldnt be. This is THE product for applying Fluid film NAS (not aerosol spray). I had some doubts (as did other folks), because I was expecting the fluid film to be liquid. It really isnt, its almost like a gel. THIS IS BETTER, because the applied product (as opposed to the aerosol spray cans) is much thicker. This sprayer worked PERFECTLY to apply the product (to my amazement!) You could adjust the flow to your needs, and the pattern was very predictable, so there wasnt much overspray. I ended up using 2 gallons of FF for my CX-9, which is a bit more than others (Ill probably put a gallon and a half on my wifes Malibu. The thing is, I live in Buffalo, and I dont know if youve heard the news, it snows here. So i put a pretty thick layer on, but no drips at all! The included wands allow you to get in to hard to reach areas, and inside the frame. SO HANDY! I used the thing for 5 minutes, and went inside to exclaim to my wife how much I love when people engineer things properly. This is engineered and built properly (in Italy, not China). Just buy the thing. You can thank the random guy on the internet later.
