Same quality product as the aerosol spray but a liquid formula that comes with a separate refillable trigger spray which enables fine misting which improves coverage
ENSURE YOU KEEP IT OFF THE BRAKES. Use ACF-50 anywhere, except the brakes, on your bike including the engine& exhaust (will smoke on first start and burn off down pipes but still slows down corrosion process). Safe on paintwork, most rubbers & brings up black plastic trim a treat.

'It should probably come supplied with every new bike!'

ACF-50 (Anti-Corrosion Formula) was originally designed to protect aircraft from existing and new corrosion and is now available to motorcyclists. Aviation products have to meet rigorously high standards & ACF-50 not only meets these but has been awarded Aviation Approvals - MIL-SPEC 81309 types II & III which means it is 'approved for ferrous and non-ferrous metals, electrical systems and electronic components'.
The US Navy carried out tests using ACF-50 on the jets on their Aircraft Carriers. They found that ACF-50 so significantly reduced the corrosion they had previously experienced they now use ACF-50 all the time! It works in that type of harsh environment so imagine how well it's going to protect your bike!
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 & 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 bikes that are used all year round.
A superb service spray as ACF-50 is also a lubricant and penetrate (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.
ACF-50 holds written OEM approvals from the following manufacturers: Douglas/Boeing Helicopter, ATR Regional Transport, Bell Helicopter Textron, Gulfstream Aerospace, British Aerospace, Concorde Battery, Raytheon Aircraft, Rolls-Royce, Learjet, and Canadair.
