Woolwax One Gallon Auto Truck Undercoating Corrosion Inhibitor Thick Fluid Coating Long Lasting Resists Wash-off Film Barrier Protects For 2 Years and More. BLACK

I’ve been using Fluid Film and that’s a good product. This year we did one truck with Woolwax and another truck with New Hampshire Oil Undercoat and wow what a difference. The Woolwax stays in place. The New Hampshire oil is super runny and a lot of it dripped off the truck after a few days.Bottom line, I like the Woolwax the best because it stays in place like the Fluid Film but it doesn’t smell as bad as the Fluid Film. Either way, the smell goes away in a few days.

The ease of spraying was what I liked the most. I’ll be selling this concept to other customers in the future.

If you want a permanent solution for stopping rust this is what you need! This stuff goes on without strong odor and washes off your hands easily, but stains your clothes so wear something you don't care about. The clear is hard to see and if you are spraying it over rust you'll still see the rust, the black works better for that. As with anything the better you do the job the longer it will work. It will creep into pinch welds and other places that moisture gets and seals it up. I would never ever get any type of undercoating that hardens up to stop rust or seal against rust. The type like the rustproofing places uses goes on over anything that is on the metal and will seal in the moisture and dirt and when it gets hard it peels off and the rust is way worse than before it was coated in the first place. I will tell you that if you think that 3 quarts of black and 1 quart of clear will do the job, order extra and save yourself the waiting time for the next gallon to come. I used 2 gallons of black and 2 quarts of clear to do my 2000 F150 and I just got one more gallon to do the areas that I didn't have enough to do, I'll be taking out my taillights and spraying everything in that area, and my front fenders where the front door hinges are. So just order about double what they tell you and have enough to do a re-coat later if you don't use it all. I hope this helps!

This product worked perfectly for undercoating my 2006 Toyota tundra. It went on easy and did not drip much at all. I recommend buying the wool wax gun to apply. I applied a heavy coat and used less that 1 gallon.

I used this to coat my 4Runner chassis inside and out. The smell wasn’t bad at all. Overall very pleased with the black since it is easier to tell where you sprayed. Buy the wool wax gun, it works well. I heated up a pot of water and kept the bottles in hot water until I was ready to spray. Also I’m glad the company switched to plastic jugs instead of metal cans

Exactly what I wanted and the new bottle is alot better for pouring

Employing Woolwax undercoating, with Woolwax's gun and an air compressor, I was able to do my F250 by myself. Once you figure out the nozzle, the undercoating goes on consistently without any harsh chemical smells, drips, or splash back. I was worried that I need a ground cover, but the undercoating stays where it is sprayed. Don't read too much into the pictures, I recognize that I missed spots. Getting a little long in the tooth to be crawling under vehicles, but I think I got the spots that mattered. I'll add that 1 Gallon was sufficient for a light coat on my truck. I didn't coat every inch, but I hit the frame pretty well, and body seams. I've got a solid quart left.

This is my 4th year using woolwax. This is a great product. After the first application I am now treating every 2 years. It just stays on that well. Also after the first application it takes a lot less product. Maybe 1 gallon the first time and 1-2 quarts the second time, especially with cars.The kit does make the whole thing a lot easier. I am using a regular full size air compressor, around 120 cfm I think. Ans it does the trick fine long as your oil is warm.
