I know, I know, rust isn't really a big problem with steel frames. Nevertheless, it would be nice to find a way to prevent, or at least significantly reduce, corrosion inside frame tubes. FWIR, sprays like Framesaver and Boeshield work pretty well, but it is challenging to coat all the interior surfaces of a frame.
I just read about a technology I'd never seen before, and I'm wondering if anybody knows about it. It is called "Vapor Corrosion Inhibitor" (VpCI) and it works, ostensibly, by releasing vapors, the molecules in which attach themselves to bare metal and form a protective layer. At least one company is selling this stuff in small strips, which could fit inside the tubes of a frame. Might this be a more effective way of protecting a frame than trying to coat it with a liquid? In theory, anyway, the VpCI vapors would migrate into all the tubes.

My father was a tool maker prior to retirement. He kept blocks of camphor in his tool boxes to prevent rust. Apparently, it is still a common practice:

Meh... really? You plug it up except for the holes you'll be using to squirt it and vent it. Then you squirt in the amount recommended by the instructions, and you rotate the frame around in the air for a while. Then to be thorough you do it again after however many hours. Look down a seattube with a flashlight on a frame that's been treated with this approach. I've only ever seen a pretty nice dispersion of the nasty toxic sludge in question, all set to be carried around with ya forever.
PS: Hopefully you'll also see a drain hole in the BB, which every single steel frame ever should have.

There is a brush applied coating that is used on the offshore oil rigs that we are investigating for use on a new line of steel bikes we are considering bringing in. I think it is made by Ameron or Rust-O-Leum. Last week an industrial paint salesman told me that Exxon may have a similar product in their industrial chemical line.
Last year we met with one of the Taiwan frame builders at Interbike. They gave us a selection of steel tubes to take back. I coated the tubes with different compounds. The untreated tubes have surface rust on them. They were just sitting in our warehouse, never outside. Tubes with a phosphoric acid component coating did just fine, but it may not be tough enough to stand up to years of rain and weather changes. That is the reason we are looking into the marine coatings industry for product candidates.

Thing is, steel bikes with typical wall thicknesses have generally been getting along fine without it forever. Really, they have. Regular use in marine environments or salted roads, or walls below .5, sure, the story is different. But it's just not an issue for most bikes. So why pump out more toxic [censored] and give the producers of said [censored] more money? And since internal rust is generally only ever an issue on bikes seeing long-term use, whatever treatment you use is going to have to last quite a while in fairly severe conditions to be all that relevant.
And if you care about internal rust, it would be completely absurd to have internal rust protection before shelling out for a drain hole on the BB.
