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 use. Coverage is roughly 200 sq. ft. per gallon based on proper thickness of 5 mils dry (6.5 - 8 mils wet). 1 Case of 12 aerosol cans is enough to properly treat the average passenger car vehicle's under-body. 

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.

    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.
