Woolwax 5-Gallon Auto/Truck Lanolin Undercoating 5 Gallon Pail. BLACK

I've looked for the best undercoating product and have mixed my own in the past. But, crude oil products degrade rubber, causes it to swell up with time so that caused some fear, especially on a newer vehicle. There seem to be so many products out there for undercoating, but what I like about WoolWax is that it is pretty much non-toxic, safe with rubber, seems to stay on for approximately 2 years (touch ups recommended), and generally it's a good product that does not degrade or break down with time, especially on non-exposed areas (cavities!) I loaded it into my generic pneumatic undercoating sprayer, and found that it is incredibly thick and hard to spray. However, if you heat it up to about 70 or 80 degrees in a separate container, it seems to flow a lot better. I've read you can apply it with ease, with an airless paint sprayer especially for the final coat underneath. As we head into winter, I've never felt so good. I know my vehicles are protected underneath and inside all cavities. I've owned many older vehicles that were completely rotten and it is not fun replacing rocker panels, welding in patches for fenders, etc. and matching up the paint and blending clear coat, and once the rust starts it is almost impossible to get under control. I pop out every rubber plug and fill every hole, cavity, fender, frame hole, with this stuff, including inside my doors. Keep the rust from starting on the inside, and/or the outside. I did use rubberized undercoating once and that vehicle is completely rusted underneath after about 3 years. Not a good choice, as the rubber breaks down and cracks, allowing saltwater to enter and become trapped underneath. I've thought about woolwax many times, but never bought it. I used about 1 gallon for a full size truck, not bad, and as I re-apply it next year I will probably use less, but I will always keep a pail in stock, it never goes bad, and neither does the metal to which it is applied.

Working good so far. Only dislike is black graphite is hard to get off every thing. Thought this would be easier to see when applying and more appealing looks when done. This was my first time applying under coating. Next time will get without black.

Messy as heck but if you want to save your undercarriage from rust, this is it. Stays tacky and doesn’t harden so you can still for a wrench or socket if you gotta work on it

I use this product to protect the frames of my rental Golf carts. It’s works great and also makes the underside of the carts look new. It does not dry so be careful when working underneath. I am very happy with the results and always recommend to others.

Woolwax is the best undercoat you can use in the northeast! It does not dry but thats what you want for maximum protection.

I live in the Midwest and drive old vehicles. This product really helps with the road salt and rust. It sprays nice out of the woolwax gun and covers very well. The smell is not too strong compared to some of the old kerosene/oil methods and has pretty much vanished after the first few months. I watched many reviews for these type of products online and woolwax seemed to last the longest. I haven't had it long enough to speak on the durability yet, but I will update the review if I am unsatisfied. I had enough product from this 5 gallon bucket to do 100% underside coverage on 3 full size pickups.

Great ty much

Worked ok fluid film is better

Good product and looks decent when the frame and undercarrige is all done

Easy to spray & stays on vehicle with no dripping.
