09-44350 - ACF-50 Anti-Corrosion Lubricant - 13 OZ Aerosol Can

ACF-50 is an active anti-corrosion compound and does not dry completely like a paint or hard coating. Instead, it forms a thin, moist, protective film that actively penetrates corrosion-prone areas and displaces moisture. This oily film ensures continued protection by inhibiting corrosion at the molecular level over time.

Yes! ACF-50 performs well on chrome surfaces and is safe to use on chrome exhaust systems. It helps protect against corrosion without causing discoloration or damage. For best results, apply ACF-50 using a clean microfiber cloth to ensure an even, thin layer and to avoid streaking or residue buildup.

No, ACF-50 is not intended or approved for use inside light aircraft fuel tanks. Its formulation is not compatible with aviation fuel and could potentially interfere with fuel system components if introduced. The manufacturer explicitly advises against using ACF-50 in fuel tanks, regardless of FAA certification, due to safety and performance concerns.

ACF-50 is effective at neutralizing and halting light surface corrosion, especially on aluminum and other common aviation metals. It can visibly improve mildly corroded areas by penetrating and lifting corrosion products. However, it will not remove active rust (oxidized iron); any rusted areas must first be cleaned or treated before applying ACF-50 to prevent further corrosion.

ACF-50 Anti-Corrosion Formula has a shelf life of approximately two years from the date of manufacture when stored properly. To maintain its full protective capabilities, it should be kept in a cool, dry environment away from direct sunlight and excessive heat. Always refer to the product label or manufacturer’s documentation for the exact expiration date.
