: Remove all grease, dirt, and existing oxidation before application.

Protecting Performance: A Guide to CM352 Corrosion Inhibitor is a high-performance corrosion inhibitor

Reapply the inhibitor at regular maintenance intervals, matching the grease schedules in your owner's manual.

: Adhere to manufacturer recommendations, such as Hartzell Service Letter HC-SL-61-364, which suggests re-applying CM352 at regularly scheduled lubrication intervals.

Achieve complete passivation with significantly lower parts-per-million (ppm) concentrations.

Wipe the surface down completely with a lint-free cloth. Do not use high-pressure air that might drive moisture into open gaps.

High-performance corrosion inhibitors are essential for protecting cooling system components and other metal parts from electrochemical degradation and galvanic corrosion.

: Using specialized inhibitors like CM352 reduces the need for expensive repairs and part replacements, potentially extending equipment lifespan by up to 250% in harsh conditions.

CM352 is designed to protect intricate areas that are prone to "crevice corrosion," such as: Staking pins and holes Mounting bolt recesses and side walls. Counterweight surfaces that are otherwise difficult to seal.

The decision to use CM352 corrosion inhibitor yields significant economic and safety benefits. For aircraft owners and maintenance facilities, the primary economic advantage is the prevention of costly corrosion-related repairs. Corrosion damage to propeller counterweights can necessitate part replacement, extensive rework, or even complete propeller overhaul—expenses that far outweigh the cost of regular inhibitor application.
