Works great. I use it on my firewall. I have a liquid cooled engine. The radiator overflow bottle tends to splash a little during start up and shut down. This works great at keeping my firewall corrosion free

Great product !

I use this on my firewall

!!!! EXCELLENT !!!

best product anyone can ever use to prevent corrosion. you can literally spray it anywhere you like.

Excellent product and service

Timely delivery, well packaged.

Best purpose built product. The mechanics use it in bulk as a fogger in the wings and I use it occasionally in the nose and tail areas.

Had a shop apply this behind my fuel tanks all along the spar to my Cherokee 160 after inspecting the tanks. Not part of the Service Bulletin but a good way to prevent future problems. Its good stuff, Ive used it on a few spots of my plane before and it changes to a dark colour immediately and the loose stuff wipes right off. Just be really careful about broad applications with it if you have an old bird like mine... This stuff has been known to cause smoking rivets real bad and can stop one problem while creating another. Use it sparingly if you can and only where needed to avoid this.

Needed some extra protection on aluminium and metal parts. I read ACF-50 ANTI CORROSION FORMULA is mil spec and controls corrosion. Long story short, if its good enough for jets, its good enough for my Porsche. Great stuff.

Protect expensive metal/Parts. Easy to use. I use 13 oz cans but other quantities for other users.

Beat corrosion preventer ever

I bought the Aerosol can, its the best anti corrosion for planes. Another A&P asked me who did it because it was so well done, proving you don't need the fancy spray jet. This tackles existing corrosion, whereas LPS3 is a wax based substance which SEALS IN, so you need to scrape any corrosion if using the LPS whereas with the ACF-50 you can also apply on top of light corrosion.

The spay bottle works great for me! I wish I would have known about this stuff 20 years ago!

I have used both the can and bottle form of ACF 50. it gets into all areas, seams, gaps. I would not use it on fresh paint or in an area that I was going to paint soon.

Great product but the bottles leaked in transit. Lost about 20% due to leakage.

Package arrive safely. However, noticed that some of the liquid had spilled out of the bottle that the packaging paper used inside the box is wet. Please improvise on this and you are ok. Other than this, cant wait to use the product later...

Great product, rattle can has mediocre pressure. With spray tube on, it's good for distance - nozzle by itself is better for a fine mist. Could benefit from more pressure in can. But in bulk with a proper fogger, this stuff will be unbeatable.

ACF-50 has been a staple in my hangar/airplane/garage/boat/cars/window frames for years! Ive used it on practically everything - my only complaint is the aerosol can loses its charge and I have to throw away 1/3 to 1/2 a can every time?! Im thinking about buying the sprayer - its just not convenient

Not enough propellant. the can still had what felt like a third of the contents when it ran out of gas. A good enough spray to begin with but it didnt last. I cannot speak for the effectivity of its anti corrosion properties in the wing where I just sprayed it and I did get a wings worth (barely) out of each can, but I am disappointed in that it went flat so soon.

The spray bottle included with the 1qt kit doesn't spray correctly. The acf-50 is too thick for the spray tip of the spray bottle that gets pumped up. The pump up bottle capacity is way too small to do any good for annuals. It takes too much time to work with the hand spray bottle. Don't expect to actually use the spray bottle included. No usable distance range from the white semitransparent plastic spray bottle. The aerosol cans work very well for long distance work and when you press the nozzle all the way down they distribute with a wide spray pattern. I plan to upgrade to a garden sprayer with the larger quantity amounts of acf-50 because the aerosol cans don't hold enough for the price. The acf-50 gives off a pleasant odor, an improvement over the other material that has been used for decades in aviation before acf-50 came out.

Bought two 13 ounce aerosol cans. Both ran out of propellant after about 4 ounces
