If rust is porous that means that water can pass through it. This means that when the surface of a metal rusts it 'exposes' fresh metal underneath to water, meaning that that rusts too.In short, rust being porous means that all the metal is effected not just the surface.
When Aluminium rusts it forms a hermetic (waterproof) layer which actually prevents further damage. That is why aluminum does not have to be as heavily protected as iron (which should be painted or galvanised to waterproof it)

There are two types porous and non porous. You can also seel porous concrete to make it non porous.

No but you can make them non-porous by putting a satin acrylic finish on them.

To make a porous material non-porous and seal it from stains, bacteria, color fading, etc...
It is currently too expensive to make it worthwhile :)
To make concrete non-porous, you can add a waterproofing admixture during the mixing process. This helps to reduce the absorption of water into the concrete, making it less porous and more resistant to water penetration. Additionally, you can seal the surface of the concrete with a waterproof sealer to further enhance its non-porous properties.

Steel is typically considered non-porous due to its dense and solid structure. However, certain types of steel can have micro-pores or surface imperfections that make them slightly porous. Generally, stainless steel has better resistance to corrosion and is less porous than other types of steel.
Well porous means it has holes in it, for example spongebob. And a porous container is probally like a container that has holes in it or indents that dont make a full hole. Like if it was a cup and you put water in it it would flow out. But if it was indented that looked like a circle that can pass as porous too.
