woolwax 12 Oz Undercoating (12) Cans Lanolin Aerosol Spray Straw (Clear) Rust Inhibitor and Prevention, Anti Corrosion Lubricant, Spray Can Extension Wand with Spray Trigger

I much prefer this to the air compressor applicator. This is the least messy way to apply woolwax, and the cost is almost a wash versus buying bulk and spraying with the air compressor applicator. I go through about 4 cans on an average vehicle. Your car will have a mild "petting zoo" smell for a couple days after but there are no strong solvent smells or anything noxious with Woolwax vs FF.

I've always been skeptical about the lanolin ready to use aerosol versus the pail that requires heating and/or thinning, but the woolwax provides more than a name but a quality product. If you've ever used white lithium aerosol spray lubricant, expect that consistency with slightly less drying. It penetrates crevices better than the thicker non-aerosol but is thinner so may require a 2nd application after a couple of weeks just to allow the 1st coating to stabilize. There are inferior products to woolwax with a much lower flash point, so beware of using non-woolwax products in your engine bay or around the exhaust. On a side note my shipment was received with the conversion sprayer and the extension nozzle crushed, not because of lack of packing, but because it was obviously dropped from quite a height. Kellsport has provided a replacement without having to hassle with fedex, which is a problem shipper in my area.

It applied easy. Tip popped off occasionally. Easy to put back on. I have the spray gun too but this was just as easy. Worked good on my car. I didn't put as much on as with the air compressor spray gun. Not as wide of coverage but it is good

I’m absolutely thrilled with the Woolwax 12 Spray Can Undercoating Kit! As someone who doesn't have a compressor, I was looking for an easy, effective way to protect my vehicle from rust and corrosion—this kit is exactly what I needed. The aerosol can is super convenient, and the included conversion trigger turned it into a spray gun with ease. I especially love the 24" extension wand with a 360° nozzle—it allowed me to get into all the tight spots like inside the doors and other hard-to-reach areas. What really sets Woolwax apart from other undercoating products is its thickness and long-lasting protection. It’s formulated with more woolgrease, making it much more resistant to wash-off compared to competitors. I feel confident that this undercoating will stand up to the elements, and since it doesn’t dry, it keeps protecting the hard-to-reach places, like seams and folds of sheet metal, all year round. I applied it in no time, and it’s already made a huge difference. If you’re looking for a reliable way to protect your vehicle or outdoor equipment from rust, especially if you're in an area that gets snow and salt, this product is definitely worth every penny. I’ll be using it annually to keep everything in top shape!

I just sprayed this on today but it looks like it will do what it claims. I did a two door mini cooper hatchback and was able to do all the doors, hood, and hatchback with two cans. The hood and area surrounding has a lot of cavities. I expect to use another 2-3 for the underside of the vehicle. I have recently bought waxoyl for my pick up truck and it like that stuff but it’s much more expensive and difficult to use. I think I’ll be sticking with wool wax from now on. I do like the waxoyl cavity wax a little bit better becuase it dries harder but there are positives to both products. My only complaint is that the straw pops off when the wand is attached and I sprayed some inside the car when doing the hatchback. The waxoyl spray wand is much better and goes straight. The wool wax wand is curved from storage and won’t straighten out.

Works great freeing up bolts and rust protection for cars

Previously for the last few years I’ve used Fluid Film. Wool Wax is something else. It goes on thicker and less susceptible to wash off. I’ve used it on a Outback, Sequoia, and Tundra. The Toyota’s took at about 10 cans each. The Subaru took about 6-7 cans. I got it everywhere underneath and am very pleased. Couldn’t have asked for a better product. Smell is noticeable, but not as strong FF. It’s been over a month now and smell is almost gone. If you live anywhere in the Rust Belt this would be a perfect annual maintenance item. Very pleased and going to use it every year going forward.

I sprayed the cars wheel wells, especially the lip area and the door inner panels etc. nearly completing the 2nd winter now on this application and it is still there, and I power wash at the shop weekly in the winter, including spraying the MN crud (salt, ice, brine, dirt) out of the wheel wells.. so a bit abusive to the coating imo, and I can run my finger inside any of the 4 lips of the fenders and still feel the coating... The undercarriage parts I hit, shock mounts etc I can't see unless I get it up on a lift- but I assume the same result. probably purchased way too much when I bought a 12 pack considering I have only used 4 cans between 3 vehicles and 2 of those vehicles have seen less than 1200 miles and summer only driving since application. I am about 25,000 miles since application on the impreza and all good
