Can’t say you right or wrong? But in this instance I believe you are right


According to this correct!

Rust is iron oxide

Iron oxide is the byproduct of chemical reaction between iron and oxygen, usually in the presence of water

The chemical reaction which generates iron oxide weakens the underlying iron by consuming it

A chemical reaction which converts a refined metal into an oxide is called corrosion

You don't see corrosion, you see the byproduct of corrosion. "Rust" is the byproduct of iron corrosion. If you see rust then you know corrosion is occurring.

Turns out the Chinese are very good at developing cheap AI as well.

I don't doubt what you say, but how many local contractors are using German tools? You can buy a German screwdriver for ten dollars, or you can buy one from Walmart for one dollar. A screwdriver is a screwdriver.

Wire brush the threads, paint on the black POR 15. Three coats. Use a search engine to find it. Available in quarts or six pack of small cans. Pricey. Do not get it on your hands. Avoid the fumes. Leftover material is useless unless the can is perfectly sealed after use. I transfer leftover POR 15 to a small glass jar sealed in plastic for preservation for future use. Commonly used for car frame, car rust restoration. The best stuff available. I wear a respirator and gloves when using it. Good luck rusty metal restorers.

Would old fashioned Navel Gel, or the grease like product you coat battery connectors with to prevent corrosion be a less dangerous solution than something like the POR 15 that requires such drastic measures ?

Down the road (over time) but right now it just rust.

Looks like to me rust and corrosion are the same or will eventually be the same over time. Can metal rust through without corrosion?

No. Rust is the byproduct of iron oxidation. Iron oxidation creates rust. Iron oxidation is a chemical reaction between oxygen and iron. Chemical reactions affecting metals are corrosion.

Rust == iron oxidation == chemical reaction affecting a metal == corrosion


There are many types of chemical reactions/corrosion; with iron, oxidation/rusting is one of them.


Bottom line, whether you accept that rust is a sign of ongoing corrosion or not, does it really matter? You know that the pipe is slowly deteriorating and something needs to be done to stop it.

Use a wire brush and paint it.

Mmmm, not really, depending on the alloy especially with Phillips/cross point screwdrivers.

It would, just like older cars the development oil leaks the metal never rusted in that area. IMO grease would eventually dry out unless reapplied plus in sun could melt it or dry it out quicker? IMO Paint preventer would be better if prepared properly.
