• just finished putting another group together to finish something

    I cleaned up the stem with, but hope i can polish up the seat post
    dremel methinks

    Nice parts.

    I don't know how much polishing you've done so don't take my advice as patronising...

    If you get a 90 mm ish wide x 200ish long strip of thick rubber, leather or even some flexible plastic (like a strip cut from a washing up liquid bottle and use that as a backing for wet and dry sand paper you should be able to clean up the seat post pretty quickly. The backing piece should stop the sandpaper rounding over the edges of the milled grooves. Start with something quite coarse like a 400 grit or coarser depending on how bad the damage is. Work your way through to 1500 then use a polishing/buffing wheel set, like this;

    That kit will last years + years of bike restoring.
    Stick it in a drill (you'll need a mop arbor which has a conical reverse thread -cheap), use a vice or even clamp it to a table. It'll give you amazing -like new results.
    I've polished up a lot of parts and usually the finish is too blinging but its good to get to that perfect finish then knock the shine back with some fine wire wool.
    Put on some good music have a drink or whatever and zone out.

    The initial stages of scratch removal with the coarse paper is where you need to be careful not to alter the shape of the part or make more scratches.
