Undercoating In A Can, Black Wax Coating in a 12 oz. aerosol spray 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). 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.

    Just what I was looking for

    Posted by CJ on Jul 09 2020

    After a long time researching wax-based undercoatings for my personal vehicles, I found this product. Living in the rust belt, I needed a product that covers well, self-heals, and was NOT a rubberized coating that would trap moisture and flake off. Voila! Undercoating in a Can! The Black formula helps hide existing rust, bringing the frame back to a uniform color, it goes on thick and dries quickly. My only gripe (and this is just personal preference) is that this stuff comes out of the can QUICK making it difficult to apply with finesse in tight areas. I just used this product for the first time this week, so time will tell if it holds up. So far, I’m a happy customer.

    Under Coating in a Can

    Posted by Bill on Jun 11 2020

    I bought this because our Hyundai Elantra has a waxy undercoating, which got wiped off in places while working underneath the car. This was the only product I could find that wasn't "rubberized". It turned out to be very close to the original. I will caution that you have to spray some on newspaper or something until it comes out in a proper consistency before you apply it.

    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!

    Best undercoating that I have seen in a ling time

    Posted by n/a on Jul 24 2018

    I live up here in the rust belt where cars don't last very long if you don't undercoat. I have been looking for a good undercoating for a long time, and all that I could find was oil based undercoating which would wash off in six months, undercoating is a can dose not it is not as messy as the oil based and after it sets up you can touch it and not get covered with oil. I would highly recommend for it for any one that wants to keep there car or truck long term . happy customer in Vermont

    So Far So Good

    Posted by Weekend Warrior on Jun 10 2016

    I pulled the RV outta storage for camping Memorial Day weekend and seen some rust on the frame rails when I leveled it up. Picked up a case of Undercoating in a Can and with minimal effort she's looking brand new.

    Best Undercoating

    Posted by Scott W. on May 31 2016

    I recondition a lot of cars and this product sprays on so nice and looks good for years. Plus to get a waxed based under coating at this price, you can't beat it.
