ACF-50 is a light carrier with a proprietary package of additives that transform it into an astonishing creeping-fluid AND an outstanding de-watering fluid too. These properties mean that just the smallest amount will get into every crevice, every blemish of corrosion, and utterly remove the water. No water means no corrosion, period. And that’s just the start of it. ACF-50 stays in place for up to a year, actively spreading, sacrificing itself to keep corrosion at bay.
