CorrosionX® Aviation takes corrosion control to a whole new level! Featuring the latest advances in Polar Bonding and Fluid Thin Film Coating (FTFC) technologies, CorrosionX Aviation is specially formulated to displace moisture, stop corrosion instantly and provide long-lasting protection. Made entirely in the USA, CorrosionX Aviation is qualified under MIL-PRF-81309 Rev. H Type II (replaces and supersedes MIL-PRF-81309G, MIL-PRF-81309F and MIL-C-81309E) for corrosion prevention and control on airframes — and now, general purpose use as well.

Used extensively by the U.S. military as well as NATO forces, all CorrosionX products and application equipment have been assigned National Stock Numbers (NSN) by the General Services Agency (GSA) and are available for procurement through the Defense Logistics Agency (DLA). Corrosion X is the only product available to the public that meets the US Navy's tough new corrosion prevention and control performance requirement ( MIL-PRF-81309H ).

Corrosion X is great stuff. I prevents corrosion on tools, guns. fishing reels and just about any metal items that are exposed to water salt and ore high humidity. I use it to restored old tools and fishing reels that are heavily rusted and completely seized up. It works better that anything else I have used and I wouldnt be without a bottle of it.

CorrosionX is one of the best things ever created if you work on anything mechanical. Its a great penetrating oil, a great lubricant, and does a nice job of stopping corrosion. I use it on everything from my lawn mower to my airplane.

I use it for everything from a penetrate to a critter deterrent. Ive abandoned conventional battery terminal protection and now solely use Corrosion X. Also, on certain vehicles that experience repetitive critter invasions and wiring damage, this has proven to be a deterrent to that. Just spray it on the areas of invasion and it seems to keep them away. Great product!!

Excellent penetrant/corrosion protection product. I use it on everything...displaces water and is safe for use on electronic equipment.

Bought the sprayer bottle. Would not stay primed. Pump would not work well. Very messy. Buy the aerasol or provide your own sprayer for the bottle.

Like previous reviews said. The pump sprayer is a waste of time. I figured enough time had passed and Corrosion X had resolved that issue. Wrong! Great product...just in a poor dispenser. Go with the aerosol.

Cap is impossible to remove. No slot like a paint aerosol . I tried to pry it up with a screw driver . Broke the cap , punctured the can . Go with the other product .

Q: I have a PA32R that I want to treat for corrosion prevention. How much Corrosion X will I need?

Per the supplier, 75 oz to a gallon should be enough for this aircraft.

Q: What is the difference between Corrosion-X original and Corrosion-X Aviation Formula? How much would be needed for a Cessna 182 Q? Thanks

Per the supplier: No real difference at all, the aviation formula just meets all the specifications necessary for aircraft use. Please use the recommended amount for the Piper PA32 (Posted in an earlier Q+A) as a guide for how much you will need for your aircraft as there is no exact amount required for each aircraft application.

Q: How do you apply Corrosion X in a spray form for best coverage?

We offer spray systems for gallon and larger containers of Corrosion X. You can view them on our web site. Refer to part numbers 09-00372, 09-00371, & 09-00373 for basic models.

Q: Is this good for cables and pulleys or is there something more appropriate?

Corrosion X would be great for that application. As always though you would want to verify with your manuals and A&P if you are using this on a certified aircraft.

Q: Will Corrosion X harm painted surfaces?, Id like to coat my ruddervaders and associated parts, they are made out of magnesium.

It is safe to use on painted surfaces and magnesium but it will not bond to paint. It will run off a painted surface.
