You want to remove only the corrosion, not ream out the tube, that will weaken the tube and make proper seatpost fit impossible, ruining the frame.
LIGHT abrasive to remove any rust, then you can try a light coat of clear laquer to seal, make sure it dries for days, then a new seatpost with lots of grease.
A Brake cylinder hone will work fine if you stroke it right.It will leave a nice "cross hatch" pattern & hardly remove any tubing material.Just remember to keep the stones lubed.
