First time using ACF-50, so can not comment on how good the long-term benefits are in terms of fighting corrosion. But I will say this... its very messy stuff to apply and the spray bottle did not spray... it just leaked all over my hands instead. It may be worthwhile getting a good quality spray bottle to apply this stuff, unless you are want to ensure your hands dont corrode for the next year or so.

Q: What is the shelf life on ACF 50? Thank you, Ed

According to manufacturing certs, this product is best used within 2 years of the date of manufacture.

Q: How does ACF-50 do on chrome? Is there any discoloration? Is it okay on chrome exhaust?

This product works great on chrome and should not cause any discoloration. Should be fine on a chrome exhaust. ACF recommends using with a micro-fiber cloth.

Q: Can this product be used on the underside and the wheel wells of an automobile? Corrosion is being caused by exposure to sea air moisture. Corrosion is predominantly on the drive shaft and frame.

Yes, This is an anti-corrosion material which can be used on aviation or automotive applications.

Q: If the surface already has corrosion, will the application of this material visibly remove the corrosion? How many aerosol spray cans would be needed to cover the underside of a full size pick-up truck? Can any paint sprayer be used for application?

Per the manufacturer: If the surface has corrosion then yes, it will visibly remove it, but if the surface has rust then no. It will not remove rust. The customer would have to clean the areas that have rust and then apply ACF-50 to prevent any more rust from appearing. Tough to say exactly how much you would need. I would think at least close to a 4 liter jug, just guessing of course. Yes, you can use a paint sprayer and that would require more product.

Q: What applicator can I use for this ACF-50 Anti-Corrosion Block Compound?

ACF-50 has applicators to use with their products. We have added them as "Accessories" to this webpage.

Q: Is ACF-50 FAA approved to be used inside light aircraft fuel tanks to provide a corrosion inhibiting coating?

This is not recomended to be used inside light aircraft fuel tanks. This is not an area where ACF-50 was designed for as it would mix with the fuel and can cause other issues. It would not have anything to do with an FAA approval, it is just something that is not recommended by the manufacturer.

Q: Does ACF-50 dry or does it remain moist as an oily film?

The ACF-50 is active so there will always be a bit of film.

Q: Is ACF-50 safe to use on a bonded aircraft structure such as a grumman yankee? Will it attack or penetrate the bond material?

ACF-50 will not negatively effect bonded structures in any way...and is perfectly safe for "all" composite aircraft structures....including the Grumman Yankee and Tiger...

Q: Can ACF50 be shipped by air? is it considered hazmat?

Only the aerosol can is considered HazMat for shipping. The non-aerosol can be shipped air without additional fees.

Q: Can the ACF-50 corrosion block be used on the interior of an aircraft? I have light corrosion on the floorboard beneath the copilot and pilots seats.

Yes, it can be used inside the aircraft.
