Seatpost still stuck by the way. Does anybody have opinions about whether other types of penetrating goop work better than Liquid Wrench? Also, does the penetrating goop lose effectiveness over time as volatile ingredients disappear?
Kroil is a possibility... is there rust on the visible part of the alloy post in the crack?
[MENTION=498403]Mad Honk[/MENTION] suggested removing the bottom bracket, flipping the frame and putting an ATF/acetone mixture in the tube from the bottom and letting it sit. If it isn’t a fluted post it will seep into the crannies and provide lubrication. Problem is that it isn’t rust...it’s the Aluminum Oxide deposits that are unaffected by derusters.
i have used parallel 2 by 6s for leverage with the seat on to twist but it is risky.
