Strike Shield

Spray Shield

When comparing the characteristics of SPRAY-SHIELD™ (SS) & STRIKE-SHIELD™ (STKS) to those of WD-40™, there are profound differences in product features and benefits.

WD-40 Claims Five Basic Functions:


WD-40 gets under dirt, grime and grease to clean. It also dissolves adhesives, allowing easy removal of labels, tape, stickers, and excess bonding material.


Because WD-40 displaces moisture, it quickly dries out electrical systems to eliminate moisture-induced short circuits.


WD-40 loosens rust-to-metal bonds and frees stuck, frozen or rusted metal parts.


WD-40's lubricating ingredients are widely dispersed and hold firmly to all moving parts.


WD-40 protects metal surfaces with corrosion-resistant ingredients to shield against moisture and other corrosive elements.

SPRAY-SHIELD & STRIKE-SHIELD Provide The Above Functions Plus More:


SS & STKS lift and remove dirt, grime and grease from surfaces, including adhesive compounds and bonding agents.

SS & STKS keep surfaces clean by rejecting airborne contaminants, such as dust and smoke, due to its electrochemical surface bonding technique by causing a dipole-dipole interaction and cation exchange on the metal surfaces. This, in effect, creates a greater positive charge on the metal surfaces which react with positive charged airborne contaminants (+ ions) in causing a repulsion between the two.


SS & STKS are a fast-acting drying agent for quick and thorough moisture displacement in damp or soaked electrical or electronic systems. A migrating film burrows under condensation and moisture, driving it to the surface where they dry or can be wiped off to reactivate circuits. After moisture is displaced, an ultra-thin residual film resists rust and corrosion. SS & STKS do not contain carbon tetrachloride and will not harm insulation.

Areas of Use: Wet or damp ignitions, electrical systems, motors, controls, starters, relays, radios, electronic equipment, etc.


SS & STKS are the ideal solution to hundreds of different maintenance and production problems involving rust and corrosion. They work quickly and effectively on even the most severe cases of rusted equipment, parts and components. SS & STKS disperse quickly into rusted, corroded areas to loosen scale and free up working mechanisms, tight fitting parts and frozen fastenings. SS & STKS’s low surface tension speed penetration even into normally inaccessible areas. SS & STKS will not affect painted surfaces.

Areas of Use: Rusted lugs or bolts, sliding parts, sluggish mechanisms, hinges, tools, products in storage, gear trains, wheels, rotating apparatus, linkages, cams, levers, industrial equipment, etc.


SS & STKS are a light, but lasting lubricant. They offer quick, positive, long-lasting lubrication on wide varieties of applications in industry, the shop and garage, the farm and at home. SS & STKS are ideal for automobiles and equipment, flowing and lubricating deeply into hard-to-reach internal areas.

Areas of Use: Metal mechanisms, gears, locks, linkages, wheel bearings, metal-to-metal surfaces, cams, levers, engines, motors, slides, hinges, garden equipment, etc.


SS & STKS stop rust dead in its tracks. These products’ unique formulation uses a combination of the best rust and oxidation preventatives available. SS & STKS seek out rust, stop the oxidation process and prevent further rust from forming.

In addition, SS & STKS remove corrosion and corrosion bridges from printed circuit boards after a light spray and “toothbrush” scrubbing. This prohibits corrosion from also returning in the future. After corrosion is removed and excess SS & STKS are wiped from the board, a microfilm layer will remain on the surface of the metals to virtually eliminate the long-term effects of electrolytic bridging.

Additional Features Of SPRAY-SHIELD & STRIKE-SHIELD:

SS & STKS contain Steel Shield EPA “ABF Technology”™, one of the leading anti-friction, metal-treating products. EPA is a blend of petroleum products containing no graphite, PTFE, silicones, moly or synthetics. The dielectric strength of SS & STKS is rated at 45 KV (45,000 volts).

SS & STKS are not an aerosol - they are packaged in convenient hand pump spray bottles and conforms to DOT and OSHA regulations. The adjustable nozzle allows you to provide an overall misting of lubrication or pinpoint just the areas you want with jet spray. You can also use SS & STKS with Air Pressurized Sprayer, which works as well as an aerosol, but utilizes compressed air.
