AMSOIL MP METAL PROTECTOR

Four jobs out of one can

This covers ground that normally takes four separate cans on the shelf. It penetrates through rust and corrosion to get frozen parts moving, lubricates moving parts, displaces water, and cleans, and the spray reaches into places you cannot get a brush into.

A seized bolt on a plow mount, a squeaking tool box hinge, a rusted trailer lock, and a soaked ignition connector all take the same treatment. That is what makes the small can worth keeping in a tool box or under the seat rather than back at the shop.

Penetrating rust instead of covering it

Cutting through rust and freeing frozen components is the first thing it does. Penetration depends on the fluid actually reaching the corroded interface between two parts, which is where a thin spray wins and a grease never gets started. Rusty hardware, tools, trailer locks, and off-season implements all qualify.

Getting movement back is not the same as removing rust. A freed bolt is still a corroded bolt, and the film left behind is what keeps that same fastener from locking up again over the next season on a machine that sits outdoors between uses.

Lubrication that will not gum up a linkage

It lubricates moving parts and silences squeaks without gumming up mechanisms, and that qualifier is the useful half. A heavy lubricant on a light mechanism stiffens it, collects dust, and leaves the linkage worse off than when you started.

Latches, cable ends, and pivoting brackets are where a thin film beats packed grease. Those are parts that bind before they wear, so what they need is something that keeps them moving freely rather than something that fills the gap with paste.

Electrical and ignition work, power off first

Disconnect the power source before you spray any electrical equipment. That comes first even though it shows up in the middle of the directions, and it applies to a battery-fed circuit on your machine the same as it does to a bench tool plugged into the wall.

With the power off, it displaces freshwater and saltwater moisture and is the go-to for drying and protecting electrical and ignition systems. Salt water is called out specifically, which matters if you ride near the coast or haul the machine on salted roads, where a wet connector becomes a corroded one in no time.

Leave the film alone, and handle the can right

Shake well and spray the area you want treated. For best results, do not wipe it off. The carrier evaporates and leaves the protection in place, so a part that looks wet at first finishes on its own. Wipe it and you take the corrosion protection off along with the excess, which leaves you the mess without the benefit.

The silicone-free formula is compatible with plastic, leather, fabric, fishing line, and paint. On a machine where a rusted fastener sits an inch from a plastic fender or a painted frame tube, that compatibility is what makes a targeted shot practical without masking everything nearby.

Contents form an extremely flammable aerosol with a flash point estimated at 54°C (129.2°F). The clear liquid smells like hydrocarbon, causes organ damage with prolonged or repeated exposure, and may be fatal if swallowed and it reaches your airways, so keep the bursts short and the air moving. AMP4SC-EA is the 4 oz. can and AMPSC-EA the 8.75 oz., each also sold by the case of twelve, with the 8.75 oz. size available in Canada under stock code CMP.
