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

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!

Great product

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.

Great product

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

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.

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 like it . It stays soft and doesn’t wash off easily . It’s a lot messy if you have to do future repairs,but if it keeps the body from rotting out it’s okay .

Relativ kurze Versandzeit. Kam gut verpackt an. Das das Woolwax im Kanister ist, scheint neu zu sein? Aber macht ein dosieren einfacher. Ich muss das Produkt noch testen, bin aber bisher zufrieden

Excellent product. I've used it for years on all my vehicles. It sticks well without drying out. I highly recommend this product.

This stuff I chose bc it’s black. Makes the little rust I had look better. I applied it with a paint brush. Works good but takes forever. I’m going to keep using this stuff but with a spray gun next spring. Seems to be holding up well. I think I used half a jug for my truck. Will buy again once I run out.

Très bon produit. Résistant au nettoyage haute pression. Ne coule pas

Used a full gallon on my car. Was able to do all 4 wheel wells very thoroughly AND spray 90% of the underside with 1 gallon.
