woolwaxOne Gallon Auto Truck Undercoating Corrosion Inhibitor Thick Long Lasting Resists Wash-off Odor Free Protects For 2 Years and More. STRAW (clear)

This is an excellent product. It's not one time apply and good for a decade, you have to keep it up at least every other year. But it works well and smells good. Also recommend their spray gun which is well matched to the product. Heat the bottle up with sunshine or a small electric heater, to get a thinner viscosity, then spray it on. If you have places that need touch-up, you can just brush it on with a paint brush. My 25 yr old GMC should outlast me now that rust is stopped for good. Wish we had this stuff 50 yrs ago when I lived in Cleveland.

Good price. Will buy again

Wool Wax is by far the best lanolin oil based product on the market. It doesn't wash off as easy was other products in its class. However other products are better suited for cavity coatings for areas like your doors and rocker panels. The concern is covering the drain holes with a thick product like Wool Wax. Will work great inside of frames though.

I bought it to compare to fluid film. There is no way that it is thicker than fluid film. I can easily pour it from the can into my spray bottles. fluid film I have to use a funnel and a spatula to force the materials in to the bottles . I have used fluid film for 7 years now on our vehicles and about a dozen of my neighbors vehicles also. Before fluid film I used to use Bar and chain oil which was messy for about a week after spraying. If the wool wax outlast fluid film that will be my new go to. There also is a 25-50% difference in cost on the wool wax though

I like using WoolWax much better than FluidFilm as this product doesn’t have the smell that goes with FF. To me it is also easier to apply.

Works great, it’s very thick which makes it more difficult to apply but it’s more wash resistant compared to Fluid Film so it’s worth the extra effort. It also hardly drips. If you’re spraying when it’s around 40 degrees or less you might need to heat the bottles/can to help make it easier. I used a hot plate on very low with water in a pot to warm the bottles. It doesn’t have a strong or offensive odor but you will be able to smell it when applied for awhile. Just don’t power wash the undercarriage until spring if you have to but it works fine if it’s dirty, and can build up a tough coat over a few years of continued use.

Sprayed a 99 GMC Yukon and a 95 Ford ranger.Wish I'd known about this stuff long ago replaced plenty of rusted out parts on my Ford ranger. I feel like this could have prevented a lot of those problems.First time using Woolwax, purchase their spray gun and applied at 100 PSI on a 50° F day. I'd recommend wearing a face mask and safety glasses. Especially if your vehicle is as rusty as mine was, lots of rusty debris flying around.The directions say you don't need to wash your vehicle. Just make sure and get as much of the loose rust off before applying.Hopefully this will last 2 years in between applications. I was able to do both vehicles with one gallon and had a little left over.Haven't tried fluid film or crown but am pretty happy so far with how Woolwax sprayed on a cold day for as thick as it looks and doesn't smell half bad either.

Definitely use this before it starts getting too cold, it is so much easier when it is 70 than when it is 50. I usually have a bucket of super hot water to soak the bottle in before use, and that usually will last me half of the vehicle before I refill/warm again.I have used this 2 winters on my Expedition, and I still have a third of a gallon left for spring or next fall.The difference between this and no coating is night and day. Well worth the $30 and few hours a year.
