I might do that. I've been hitting it with PB Blaster on-and-off for the past couple months, but I don't know if it's penetrated the rust at all. I've just kind of stalled on this one because I've been working on a few other bikes, and I need the bike stand to work on those. I'll figure something out. I'm in no hurry.Plug the seat post. Turn the frame upside down and fill the seat tube with either citric acid mix, or atf / acetone thru the hole in the bottom bracket.
That amount if crust may be worth acid treatment, then penetrating oil.
