Metal Protector – Heavy Duty info:

AMSOIL Heavy Duty Metal Protector often referred to as our undercoating spray, helps protect metal surfaces that require a heavy-duty lubricant or are exposed to the damaging effects of salt, moisture or chemical corrosion. Ideal for hinges, wire ropes and springs, nuts and bolts, motorcycle or bicycle chains, and for undercoating wheel wells and other metal surfaces exposed to water, dirt or road salt.

Corrosion Inhibitor

  • Contains special rust and corrosion inhibitor additives
  • Protects against the effects of salt, moisture and chemical corrosion
  • Leaves a long-lasting (up to several years), protective, wax-like, amber coating
  • Sprays into hard-to-reach places and works as an undercoat
  • Ideal for steel, iron, aluminum, brass, copper and other metal surfaces

New Rust Prevention Spray

The three aluminum pieces in the upper left were treated with Heavy-Duty Metal Protector on their lower halves, while the three aluminum pieces in the upper right were untreated. The three steel pieces in the lower left were treated with Heavy-Duty Metal Protector on their lower halves, while the three steel pieces in the lower right were untreated. Following treatment, the pieces were placed in a 5 percent saltwater bath (the same salt and a similar solution to what vehicles and equipment are exposed to on winter roadways) for one hour, removed and allowed to dry for 23 hours. This process was repeated for 10 days. As seen in the pictures, the portions treated with Heavy-Duty Metal Protector show no signs of corrosion.

Metal Protector Reviews

Unreal

By  SPC,  a  Verified Buyer  from  Chicago Illinois   on  July 04, 2023
You name it I’ve tried it when it comes to products that claim they prevent rust or stop rust and some are good don’t get me wrong I’m talking major brand names to Independent chemical companies and I figured I’d give Amsoil a try and I literally put it on existing rust and it stopped the rust not for like a week or a month but permanently and I did the underneath of my Toyota 4Runner from front to back and is anybody knows in the Rust Belt most products don’t hold up this not only holds up but I’m just sorry I didn’t find it years ago Amsoil really is the best I admit this is the first product I’ve ever used from them but now that I’ve seen what this can do I’m going to try the other products too.

Great quality product that protects all of my wave runner’s operating systems and does not easily wear off.

This stuff should be mandatory in this humid salty environment. It works great.

Great Product

Purchased this as an alternative to another product I have used for some time. The MPhd covers better and, more importantly, has staying power. finish is very durable so far.

HDMP has been a necessity in my shop for decades. It gets used as chain lube, protection from the elements on my little sawmill, hinge lube on every vehicle, on and on. Just a super useful product! Feel sorry for anyone who doesnt have a can.

Great product

By  Jon,  a  Verified Buyer  from  NY  on  May 02, 2022
My main use for this product is vehicle undercoating. It works great at protecting everything on the chassis, including subframes, suspension components, hardware, brake calipers & shields. I also use it to protect vulnerable body panels – especially inside the quarter panels and lower sections of the doors. I reapply every year or two, more often to high exposure areas. It’s helped my 12 year old car hold up well against harsh winter salt. Amsoil HDMP is a good value compared to similar products and the extension straw is nice for tight spaces.
