Undercoating In A Can, Black Wax Coating has set the standard for modern high performance vehicle rust preventatives in an Aerosol Can. Now that same product can be purchased in larger unit sizes to be used with spray equipment.

Undercoating In A Can, Black Wax Coating in 1 Gallon Can 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).

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.

    Great Product

    Posted by Dan Carlson on Apr 08 2020

    Initial impressions: A lot easier to apply than other undercoats I have worked with. It goes a long way. 1/4 of the gallon was all I used to coat the steel components of my F150. I used a sponge brush for all but a few places where spraying was need to treat a hard to reach area. Cleans up easy. I am hopeful I will still feel this is a five star rating after a year or theee on the road.

    Over-Spray Issue

    Posted by TB on Mar 28 2019

    I had a concern because I had some over spray after treating my 2014 GMC Pick-up. I was instructed by PSC that it should come off with a little mineral spirits. I ended up using odorless mineral spirits from my local hardware store and it worked perfect. Thank You PSC!

    The Right Stuff!

    Posted by Gustavo on Oct 02 2017

    I'm just going to say I spent a long time trying to find a product that was not rubber undercoat. Instead that was oil-based. Because I wanted it to stay flexible and resist corrosion. I applied undercoating in a can and it went on excellent. with minimal overspray. This is my first time using undercoating in a can so I don't know how it will hold up. It's reasonably priced and if it's stands the test of time I will definitely reorder it to undercoat my truck again. I purchased the gallons worth and was able to spray two coats under my Chevy Tahoe. I would definitely recommend this to anyone looking for an oil based undercoat!
