I was amazed at how the Woolwax performed when applied. It kind of bubbles and then spreads as it coats the surface. I used about 3 cans to cover the entire bottom of my 2008 Lexus LX. I plan to use the other 3 cans with the included nozzle to get into the frame and inner surfaces. This product gives confidence that it will provide protection from rust.

A little went a long way on my 4runner, and so far hasn’t come off and is doing its job. A plus was that it made everything it touched look super black and like new. It was a breeze to apply, (the straw / nozzle helps a ton)I live on a dirt road and it doesn’t appear to have collected too much dust either. Officially a fan, and will be using this again in the future…

Great coverage, easy to spray. Covers surface rust easily and leaves it looking nice and black. Will see how it holds up over time but it definitely does what it says it does

Little to no smell. Sprayed real nice with the extension tube, just home on to it it can shoot off and get lost in a panel. I did inside all my doors ,quarters, rockers,inside fenders, and any where else I could on my 2011 suburban, and sections of the frame that were not freshly cleaned and painted. Two of the cans did feel like they had alot left but ran out of air but still finished the job.have told alot of guys at the dealer to use on their trucks also.

Covers well. Easy to use. Takes forever to dry but maybe that’s how it works.
