The how depends on what, why, and where
My preferred method usually involves removal, encapsulation, and epoxy coating
But that's a little over-kill for a Bilco Door

You can tell that the dudes on here really know what they are doing! It's a pretty broad question and is highly dependant on what you are coating! If you are coating the inside of a chemical storage tank, you need to blast it carefully (don't drive the salts and sulfates into the metal) to white metal.
We make a solution with some acids in it that love to eat rust. Sometimes that is a good solution depending on the end use. We also make anti-corrosive primers.
Here are some options:
* Blasting
* Hand Tool Cleaning
* Chemical Solutions
* Rust Converting Primers
* Anti-Corrosive Primers
* Cathodic Protection
In general, epoxies are the top choice for rust protection.

Like many things, it claims to be the "best", but I believe in this case they have the research and track record to prove it.
Apparently, you won't need to remove every spot of rust because this stuff will lift it from a metal surface and then encase it in resin, making the rust harmless - unable to do further damage. It doesn't just 'convert' rust to that annoying black powder. And it's paintable. I ordered some but it's too cold to do auto touch-ups right now, so I can't offer a personal testimony.
Anyhow, it has a 2-year shelf life unopened, but only 2-3 weeks once opened, so be sure to order the right quantity!

If it's only slight surface rust, we wirebrush or sand then apply a metal primer (usually Kem Kromik from SW) then a finish coat.
For very heavily rusted surfaces, we've used Ospho, sold in quarts at a local paint store, then coat with metal primer and finish coat.

Awfully pretty place for chemical storage tanksYou can tell that the dudes on here really know what they are doing! It's a pretty broad question and is highly dependant on what you are coating!

Wow!
Those storage tanks are in a magnificent location.
A lot of the oilfield leases I worked on in the past were in great places, but not quite THAT spectacular!
Wonder if they'd pay ME to work there...
I can do BETTER.
Kinda ragged looking catwalk, if you ask me.
Hey Dude, is it Canadian?
