Apply a non-porous coating like KBS Rustseal that will block all metal pores and prevents moisture & oxygen from entering. Rustseal cures by drawing moisture from the air and out of steel/metal. It dries rock hard and even is strenghtened by continued exposure to moisture. It's a remarkable coating that lasts forever.

Rusting is an electrical reaction. The strange thing is if a sheet of metal is painted but has a hole in the paint the rust at that point will be more than if the metal had no paint at all! Different metals in contact with steel (Esp. Chrome) will cause more corrosion at that point as well. Hence cars rusting badly around chrome headlights etc

Steel is very easy to keep rust off of. Just make sure you get a stainless steel alloy containing Chromium. You can pasify the surface with a weak solution of acetic acid. This raises the ratio of Cr on the metal surface. The Cr oxidezes quickly, but the film that is formed adheres very strongly to the surface of the steel, preventing further corrosion and rusting!

Keeping pure iron from rusting is tougher. The suggestions given above are all pretty good. Keep a thin film of oil on it, vaccum wrap it with a thin film (plastic, polyimide, etc), or painting with something rustoleum all work well.

First, get rid of all of the existing rust or it will just keep coming back. Depending on the size of the object(s) this can be done with a rust remover (like Coca-Cola or Pepsi--no kidding!) or one you can buy at the hardware or auto parts store (ask the clerk for direction), or you can sand or grind the rust off--again, it depends on what it is that's rusty.
Then, coat the metal with something that will keep the rust from coming back, like a paint, primer or sealant.
Beyond that, to prevent further rusting, keep the object dry and especially avoid salt water (if it's a car part, this is especially helpful).
Sorry I couldn't be more specific, but I hope that helps!

Maybe the question, until you have a cure for oxygen eating metal up is how do you slow it down perhaps?

Electroplating, zinc coating as a SACRAFICIAL layer prior to oxygen getting to the metal.


Many processes can do this, however, as i have worked for one of the worlds most experienced companies in corrosion protection and am qualified in that area may i suggest that the normal run of the mill cures are as the name suggests , run of the mill.

Corrosion protection comes down to lots of variables, the component concerned, the application, and cost.

All of these factors mean shortcuts are taken in industry, unless you dont mind shelling out on product that IS AVAILABLE to do the job for 100 yrs plus!!!!

Sadly, it is cost.
I can supply and show you how to rust proof any object no matter whether you are in a saline solution, in the sea or not, but it is all down to cost.

Just keep sacrificing high coat zinc for now.

PS you may want to search metaflux or metatec as these use very high concentrations of zinc in product rather than others like top hat and the cheap brands.

You can get sheets of paper impregnated with rust inhibitor which vapourises onto metal.
Put into tool boxes they work quite well. If for machinery then make a cover of plastic and pop the sheets under it.

starve the surfaces of oxygen- using oil or a gas...

if you are talking about rust on a car or something like that it will be your environment and the quality of the paint job. Sand off the current rust and get it re-sprayed.

Good luck mate ;)

Paint, grease, zinc coating. On ships' hulls they bolt a block of magnesium which corrodes in preference to the steel (needs replacing every so often)

use oil like WD40 or some other oil based lubricant! Apply and it should form a coating into which neither water nor air can get to (they cause rust!)! Apply by spray or cloth!

1) painting
2) oiling
3) galvanising or coating it with another metal
4) putting a more reactive metal nearby (e.g. zinc)
They normally place a slab of zinc on the hull of a ship to
prevent it from corroding so quickly
