Woolwax 1-Gallon Jug. New Package. Same trusted formula. U.S.A. Made Lanolin Auto Truck Undercoating - Solvent Free - 2+ Year Corrosion Protection. Color: BLACK

Thicker than fluid film and surface shield and stands up to water better. It is messy when working under the truck, but I'll gladly take that than rust any day. Sprayed using a 6-gallon compressor and the wool wax gun today in 40-degree temps. Helps to sit the jug in a bucket of hot water while you're working and refilling the cans when its chilly out.

Good protection from road salt. This stuff seems to help a lot to combat road salt corrosion. It sprays on easy when you use the air gun and assorted wands from another available kit. I think it's going to really help with the insides of the steel boxed-in frames of our F-150s. It doesn't dry out like a lot of the rubberized or asphalt type materials. Those will eventually crack and fall off, leaving metal exposed to the elements again. In the areas of greatest road blast from tires, even the Woolwax will be worn off pretty fast, so a reapplication is advised. We're in some of the worst salted roads and, so far our 8 year old truck is looking just fine. It had started some corrosion because we didn't start using this till 3 years ago. No worse at all, since. I got an early start on my '23 truck so it will easily stay solid for years to come. These trucks will be the ones you want to buy used!

Besides Amazon leaving the box in the rain. The jug was sealed tite and tied in a bag. NO LEAKS!! I bought a $50 gun kit and sat the jug in my harbor freight ultrasonic cleaner. I set it to about 90 degrees F. I sprayed it at 120 psi and it went on nice and smooth. A nice thick layer but not too thick and not drippy. I only used about 3/4 gallon for a 2025 outback even after removing all the plastic and felt liners to spray under.

Love this stuff , in the past I have purchased the aerosol cans and get pretty good value from those but if you have a compressor and an undercoat gun this is the best value and the best product !

Very pleased with the ease in applying this product. I bought the undercoat gun and this sprays where you point. It doesn't drip on the floor. Stays where you put it. It looks great when your done. I used 1/2 gallon to do a 4runner. Going to do my wife's car next.

Good product, I just did not know that stays wet for several months after application.

Sprayed well and has stuck well.

10/10 product, this leaves a very nice layer on my frame of the truck so I don't have to worry about rust. It is not a super thick hard coat, so you wont have to worry about your frame rusting from the inside either! I will for sure do this on all my future cars, as I am from Minnesota and we see a lot of snow and salt.

This stuff is amazing. I first saw it on social media and then tried it. Now I have the gun and have sprayed about a dozen cars including four of my own. I even spray the deck of my lawn mower every fall with it. I am amazed at how long it lasts on the underbody of a vehicle. I live in Canada and the salt is terrible on vehicles and this stuff stays on the bottom of the vehicle for a good 2 years or more. For sills and doors and inner fenders (anywhere not subject to constant water) it’s probably a one and done application. I absolutely love this stuff.

Great product! Low odor and lasts a long time

Product works great and was just enough to do entire undercarriage of my truck, hoping to get a year out of it before I do my next one. I would definitely be doing a clear coat of Woolworth before the winter time in about seven months to have my frame and undercarriage nice in moist.

It has great coverage and a jug can easily do 2 mid sized cars or SUV.

Purchased this to do a touch up on my vehicle and so happy I found this product. To make it easier to pour I put the jug in a sink of hot water. Will continue to purchase to protect my frame!
