"When applied ACF-50 forms an 'Active' ultra-thin clear film that will kill any existing corrosion cells and will protect your bike against new corrosion forming. On areas such as switches or under the tank and seat, one application will last up to 12 months. Other more exposed areas will need topping up more regularly. ACF-50 has the ability to 'chemically neutralise road salt' and water will bead on contact and literally bounce off. Ideal for the bike that is used all year round in all weathers, a superb service spray as ACF-50 is also a lubricant and penetrant (without loosening structural attachments) and if you put your bike away for the winter, applying ACF-50 will ensure that moisture will not be allowed to cause any damage! Untreated moisture will creep into cracks and will not freely evaporate - ACF-50 actively ejects moisture from these areas." http://www.acf-50.co.uk/motorcycle/streetbike.htm
"ACF50 comes from the aerospace industry and the list of companies approving the product is rather serious. Firms such as Boeing Helicopter, Cessna, British Aerospace and Sikorsky all find the product acceptable, as does the FAA ... Application is easy on a bike and a tin lasts a long time. The best approach is to put a tiny blob on the surface to be treated and wait for it to disperse between any cracks. For example, the un-plated horn on our Suzuki V-Strom was an absolute certainty to corrode but it remains perfect after four years.
Any surplus can be spread externally with a finger or brush. Surprisingly, because chemically things which work are normally dangerous, ACF 50 is completely non-toxic and your finger won’t drop off if you touch it.
Once applied, the treatment lasts up to two years. ... As a by-product, it’s not a bad light duty lubricant for things like locks and cables, as well as being approved by its Mil-Spec (Mil-C-81309E Type II) for use in switches and on contacts." http://www.motorcycle-usa.com/2013/03/article/acf-50-corrosion-preventative-review/
