Undercoating In A Can Black Wax Coating is a rust preventative/rust-proofing sealant. It is a wax based coating that is cutback with a solvent that assists in a quicker drying time than you would normally find with similar coatings that are cutback with water. 

Undercoating In A Can Black Wax Coating is designed to provide the ultimate protection for the under-body of automobiles, trucks, trailers and other transportation equipment. This is a black wax product that will become firm and dry to the touch but will not become hard. 

The benefit of this type of pliable self-healing coating is that it provides outstanding chip resistance. It is also a "Rust Encapsulating" coating which mean it can be applied over light rust and will stop further deterioration.

    Black wax in a can

    Great product! Works really nice touching up the factory undercoat on my 2011 GMC also coats really nice on uncoated or worn off metal surfaces. Would love to use the large spray kit with the flexible spray hose to do inside the frame of vehicles so that's my next plan.

    Sprayed right out of the can. Warmed it up on a hot plate. 2 psi. In the cup 35 psi. @ the gun. Like butter. If I could do it anybody can.

    Wanted to give wax undercoating a try and this had above and beyond the best information and reviews. Went on great, time will tell how it holds up but optimistic. dried nice and tacky, not hard like rubberized.
