coating for sliding steel parts

I'm making a recumbent trike and part of the folding mechanism is a steel tube that slides inside a slightly larger steel tube. Both are made from CroMo bicycle tubing. If they're painted I suspect it will all be scratched off very quickly. What's the best stuff to coat / plate the tubes with to stop corrosion but allow them to slide without ripping it all off?

both good ideas. What about something you can do yourself?

What about regular use of Muc off Dry lube spray or a similar PTFE type spray?
