WOOLWAX™ 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.

Applied with minimal mess and no smell. The black makes chassis look new again while preventing rust. Buy a hand pump and install on lid which makes filling sprayer alot easier. It will go a long way on multiple vehicles.

Creeps well, stays on well and actually smells good after a few days.Don't forget!!1. Get a 3m type Painters mask. I found one here with goggles and replaceable filters for 20 bucks2. Order a Lid with a bung and a bucket pump. You need to transfer to the small bottles. In a pinch Lowes sells lids and TSC sells the pumps. (Not sure why neither sells both)3. TyVek suit. If you don't have an auto lift it'll probabley shred crawling under the car so might be a waste of money for you. Wear black clothes.Perhaps Woolwax can put together a kit that includes these items. It would save time.

Excellent product, sprays on great and makes vehicle look awesome after spraying.and no drips.

This stays "wet" for a while until you get some dust on it. Take your vehicle down a dusty road. If you have to work on your vehicle, just know that this stuff is like roofing tar, it gets everywhere long after it has been applied

I use this product to protect the frames of my rentalGolf 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.

Prepare to get messy and only wear clothes you are prepared to throw away after you undercoat.

Works wonders
