Rust stopper supreme

Been using fluid film and woolwax for over ten years on my cars, trucks, tractors and other vehicles. It has kept them rust free and looking new. Here in Vermont that is tough to do with the salt and brine they put on the roads. Highly recommended.

Nice upgrade over Fluid Film

I bought 3 gallons of this product. In the past I have used Fluid Film. Although that product works well, it tends to wash off in the “high traffic” areas of the bottom of a vehicle. The wool wax is thicker. I sprayed the bottom of my 2018 RAM 3500 pickup. A little over a gallon was used. NOTE: The outside temp really needs to be above 60F with the wool wax at room temp or it simply won’t spray. Fluid Film sprays in colder temps. So far very satisfied.

Great stuff!

Woolwax is easy to apply, and easy to clean overspray and equipment after the application. It also has no unpleasant odor. I hope this helps slow down the Wisconsin winter rust!

Ricks undercoating

Been a big fan or user of fluid film for years .Tried black Woolwax love the way it go''s on no smell ! It look's great on all lower parts of my trucks.Used it where it showed the most.Used straw color on rest . Did four jobs one weekend. Everyone very happy the way they looked.
