Undercoating In A Can Black Wax Automotive Undercoating

Undercoating In A Can, Black Wax Coating is a premium wax-based rust preventative sealant that protects undercarriages, and is designed for Commercial and Automotive vehicle, trailers and equipment. Coverage is roughly 200 sq. ft. per gallon based on proper thickness of 5 mils dry (6.5 - 8 mils wet). A single case of 12/12oz aerosol cans is enough to properly treat the average passenger car vehicle's under-body. Larger SUV's and Trucks we recommend 2 cases of 12/12oz aerosol cans for proper coverage. 

A new addition to this line is the cost effective 12/32 oz QUIK CHANGE Quarts that utilize our QUIKCOAT EZ Sprayer. With this size option, 1 case provides complete coverage for most passenger cars and light trucks.

Wax-based undercoating technology has protected United States Military vehicles (MIL-PRF-62218B) and semi-trailer chassis components, exposed to harsh, highly corrosive environments for over 50 years. This premium wax based undercoating is also the ultimate protection for your family vehicles. 

Undercoating In A Can Black Wax Coating is a "Rust Encapsulating" product meaning it can be applied to existing rust areas and will deter further compounding effects of rust (Rust Cancer). The coating has been continuously improved over the product lifetime to resist the very harmful side effects modern road salts- magnesium, calcium, and potassium chlorides.

This rust inhibiting and sound deadening sealant forms a firm barrier film when applied to metal and wood structures, thereby extending the useful life of the coated surface. This coating exhibits excellent gravel, power wash, and impact resistance. 

The latest revision of SAE J2721, for commercial trucks, requires coatings, intended for chassis components, to be exposed to SAE J400 gravel test, where high velocity stones are thrown at the film of coating, before cyclic exposure to the corrosive salt solutions. Consequently, excellent gravel resistance is vital for long term performance. Get the ultimate protection from Undercoating In A Can.

    This is a great and well priced product. I live in Massachusetts and this is my go to for the warmer months. It takes too long to dry in the winter or fall but if weather is good its the best.

    Great Stuff!

    Posted by Michael Chappuis on Apr 17 2023

    I used this on my RAM 1500 Quad Cab, I first wire brushed any rust spots, then used a bucket of water and a rag to wash the underside of the truck. When applying, this stuff goes on nice and thick and sprays out of the can very well (maybe a touch fast, but thankfully it's the underside of the truck so dripping isn't a big deal) I did the frame, and all steel parts, I did some sheet metal parts of the body where other metal was welded or drilled into it, but left the rest of the sheet metal alone. It took just shy of 6 cans (I bought a case of 12, had I don't all the sheet metal it might have used the case). It looks great when done and even after drying feels a little tacky to the touch, when water hits it it beads up and drops off, I'd almost describe it as being like an oil paint/grease. It does not come off that easily, you'd have to seriously scrub it to get it to come off. I would definitely recommend this stuff and hope it holds up well! (with 5 cans left I have plenty for "touch up" if needed.)

    Shipping was fast and on time the product seems to be what they advertised it to be it seems to spray very nice out of the cans and it covers well too. I’ll see how long the product last now under the truck. I’m over all satisfied and will do business again with them in the future.

    Nice product , sprays evenly from the can. I am using this on the frame of a cargo trailer to prevent corrosion. Much easier to apply than other brands and easily gets into all of the small crevices.
