Great product, seems to be working well, sprayed the entire chassis for salt protection and haven't seen any failing yet.

My son told me about this stuff, great product. Ordered a case of 12 large cans to spray the under body, frame, steering, suspension, on my new 2023 Jeep Gladiator, sprayed everything except brakes & exhaust. Using the supplied straw kept overspray to a minimum. Wore safety glasses & a N95 breathing mask made by 3M which both worked good. Truck stayed in my heated shop for 36 hrs after spraying to make sure it was completely dry. The mess it made on the cement floor was super easy to clean up with just regular mineral spirits. Plenty of videos on U-tube that go more in depth but I highly recommend this product. Duane.

One can did the majority of what I wanted to coat on my 2016 Silverado. Seems to do it’s job and I can see how with the wax type film.

I have used this protector on many of my vehicles. I have taken them to Moab, UT. Chicago, IL., Northern Texas, New Mexico, Louisiana, Georgia, Alabama, New Jersey...etc. and the protectant works well overall. I would tell you to check it once in a while and touch up if you feel it is required. It have save me a lot of money from possible corrosion.

Isn’t it funny how some of the coldest states in America get by just fine without covering their roads in salt? They use sand and it works perfectly. The best part about sand is it doesn’t cause anew truck to rust into oblivion 5 years later. Fortunately, for drivers in Wisconsin, our state dumps copious amounts of salt on our roads 6 months out of the year! I bought my Ram 1500 classic brand new in 2019, and every year before the first snow I coat the underside of my truck in MP HD. 5 winters later the underside of my truck still looks brand new. (I’m not exaggerating) Not a spec of corrosion, not even surface rust. All of the factory paint remains perfect preserved from the frame rails to the floor pans to the trailer hitch. My only suggestion to Amsoil, please offer a non-aerosol version so I can use my own sprayer. Sometimes trying to spray at an angle or upside down under the truck can be frustrating with the aerosol cans. Sell me a quart or gallon of the product and I’ll use my own sprayer for an easier more thorough application.

Used it on my Toro and Wright Lawn Mowers

I could not be happier with how this product applied and then dried. The underside of my 2016 F150 looks 100% better. Friends and coworkers noticed so I purchased a second case for gifts or as a thank-you. Every person I gave two or three cans to is thrilled with how their trucks came out.

use it a lot for years, good stuff

Long lasting great product for preventing rust

Love this stuff !! I spray it on everything underneath. Pickups, trailers, quad axle. Keeps the Wisconsin salt at bay ! Better than tar undercoating because it's a soft wax like coating you can work with. I freshen the coating every year and my 2011 Chevy 2600 HD has no rust ! Awesome protectant !!
