    So far So good
    By  VICTOR,  a  Verified Buyer  from  TX  on  June 06, 2025
    I recently used this product on a ground for my boat trailer. Why there is a frame mounted ground on a boat trailer is beyond me. I coated the ground heavily before immediately using the boat in saltwater and so far it seems to be doing the trick well. I am eventually going to rewire the trailer but for the time being this product seems like it will hold me over.
    Bottom Line
    Yes, I would recommend this to a friend.

    Undercoat
    By  GREGG,  a  Verified Buyer  from  MA  on  January 30, 2025
    I use this for undercoat on my truck. It dries quickly and works much better then other products that are actually advertised as undercoat. It doesn’t attract dirt. Other undercoating products do not dry, drip and need to be reapplied more frequently then MPHD.
    Bottom Line
    Yes, I would recommend this to a friend.

    D.I.Y. rust proofing
    By  DUANE,  a  Verified Buyer  from  Iowa  on  December 13, 2024
    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.

    Yes, I would recommend this to a friend.

    good metal protectant
    By  Big Bear,  a  Verified Buyer  from  San Antonio, TX  on  December 05, 2024
    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.
    Bottom Line
    Yes, I would recommend this to a friend.

    Salted Roads worst Nightmare
    By  TYLER,  a  Verified Buyer  from  Wisconsin   on  December 04, 2024
    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.
    Bottom Line
    Yes, I would recommend this to a friend.

    Watched others use this product, Now its my turn
    By  KERRY,  a  Verified Buyer  from  New Hampshire  on  November 30, 2024
    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.
    Bottom Line
    Yes, I would recommend this to a friend.

    HD Metal Protector
    By  JOHN,  a  Verified Buyer  from  Arpin, WI  on  June 02, 2024
    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 !!
    Bottom Line
    Yes, I would recommend this to a friend.

    A Must Have When Fighting Corrosion
    By  MICHAEL,  a  Verified Buyer  from  MS Gulf Coast  on  May 08, 2024
    Amsoil’s Heavy Duty Metal Protector simply works. I’ve used it on outdoor equipment, yard decorations, and especially on vehicle undercarriage components. Always a good idea to surface prep first. Highly recommend!

    Metal Protection you can see!
    By  Jim,  a  Verified Buyer  from  Oregon  on  April 17, 2024
    I sprayed the heavy-duty metal protection on our son's swing set two years ago. The waxy coating is still visible, the chains and hinges aren't rusting, and I can't imagine a better product for outdoor metal.
    Bottom Line
    Yes, I would recommend this to a friend.
