ACF-50 is a really effective rust preventative. You spray it on and after leaving it for an hour or so thoroughly wipe off the excess. It’s very messy stuff and leaves an oily finish but this does go after a while. To maintain the protection, just rub a little into the frame occasionally if any surface rust begins to appear.
I have to admit that this is not an established technique and won’t be to everyone’s taste! I tried it on a steel stem a few years ago and it worked quite well. The steel mellows with a satisfying patina - like an old spade…
Personally I love a raw finish but don’t much like clear-coat as moisture often seems to get underneath. That patchy rusting/worming that follows looks crap and is difficult to repair as the lacquer has to be stripped back.
At least an ACF-50 treated frame would be easier to maintain (if you don’t mind the messy process) and it’d be a cinch to remove if it didn’t work out
