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

Love this stuff. It doesn't have a real strong smell and it penetrates very well. I heat it up a little before spraying it. Its a bit pricy and you should reapply every year but I think it is superior to oil spraying and isnt as messy. I does wash off a bit during the summer but I prefer that because it keeps the undercarriage cleaner and not covered in dirty grease.

Good stuff. I've been using Fluid Film but thought I would give Woolwax a try since I've been using the Woolwax Pro Spray gun. I like the Woolwax product and will see how it performs over the midwest winter coming up. It is supposedly more durable than Fluid Film. I sprayed the underside everywhere except the exhaust.

Works great

easy to apply

Like it it’s for my son’s truck

I love this stuff for winter road protection. Follow the package instructions and invest in the recommended spray gun. It has helped our plow trucks stay fresh.

Doing all my cars with this Moved to area with lotsa snow and salt, so it's a necessity

It seems to do a reasonable job of coating the underside of the truck. Viscous but not as solid as you might expect. Even in 10 degree temperature the oil does not solidify so your underside will always be wet. I have not seen how summer temps affect this yet but I would imagine most of the oil will evaporate or wear off. I would expect an annual application is necessary. They make a hard coating which I have not yet tried. Overall, not bad and better than other undercoating I have used.
