Has anyone ever used ACF-50 anti-corrosion or know anything about it?

ACF 50 is used in the aircraft industry as an anti-corrosion coating on aluminum. needs re-appplying every 3-6 months. They spray interior cavities and exteriors of aircraft with liberal coats of it. (caution on painted surfaces, as it will darken paint) It's non-electro conductive, and all round excellent stuff. I spoke with one of the larger local sea plane operators about it, they swear by it.
Have to figure, aluminum aircraft, running on salt water, very similar to a defender on a salty road.
Using ACF-50 spray underneath all your body capping?s as they are not painted underneath, I have also then sprayed Dinitrol underneath on top of the ACF-50 and will keep spraying at least twice a year just to make sure nothing is corroding.
ACF-50 your bulkhead to bonnet hinges. Brown rust staining from new is present on many Defenders. ACF-50 stops it dead.
Spray also your;
door hinges and fasteners,
bonnet hinges and fasteners,
bulkhead to windscreen hinges,
wiper arms and their bases in particular,
aerial,
screws holding front grill etc,
front lower ali panel,
bumper insides,
body rivets, they can rust in the middle as well as corrode on the outside, most can be treated from inside the vehicle also,
Door seal rivets,
headlight bezels,
radiator brackets and fasteners, fan screws etc etc (alot of this can be sprayed through the grill so you don't need to take it off!),
wing mirror arm fastener cover, just cover it all and wipe off,
exterior part or rear window latch,
inside of towing electrics plug and behind,
rear of lights electrics (mud rots the wires away!)
rear tub door shut metal strip,
rear wheel holder,
engine bulkhead side and all electrics, common rail, brackets, fasteners etc etc being careful not to spray the belt and pulleys,
inner bonnet edges
any nuts and bolt heads, screw etc you can see inside the vehicle. The lower seat belt bracket bolts can rust very quickly for instance,
seat frames brackets are especially worth doing also.
