|So if I remove the paint with oven cleaner and end up with a grey aluminum post, is it possible to polish the post back to a brighter aluminum finish with 800 grit sandpaper and aluminum polish?|

|Yes it is. Start with coarse grit sandpaper and work toward the finner stuff: 400 - 600 - 1000 - ?
When your done with this, start with the polish. A buffing wheel will help a great deal toward getting that nice bright chrome-like finish.
|Sure, but it'll take time.||jw25|

|I think 800 grit paper or some fine (0 to 000) steel wool is a good start. I'd use them wet, and then start buffing with a clean cloth and something like Mother's metal polish. I've used it with good results on a couple of stems, but a buffing wheel or dremel does make this step faster. |
Once it's shiny, you may need to repolish it every once in a while, as bare aluminum will corrode slightly, and get "cloudy". Exposure to water (salty water, aka sweat, is even worse) will hasten this, but in time, it'll happen. Most polished alloy components have a clear anodizing treatment to prevent this, but it's far easier and cheaper to repolish now and again.

|just kidding ;-)
i like all the little successive posts as its reminding me of how lazy i am with my projects. im happy for you as you sound like you are having a good time scince finding your long lost frame.
yes you can polish up your post its just a matter of how much life you have in your fingers. sounds like youve polishing and scraping for a week now. im not familiar with oven cleaner but if its paint on the seat post grooves (campy style) you are trying to remove i would go with a generic auto paint stripper or at least brake fluid which you might have lying around - even some used stuff should be ok. still oven cleaner might just be corrosive enough.
oh keep some cash aside for weigle's or at least get some boesheild T-9 which is a very usefull lubricant as well as frame innards protector.
keeep up the fine work!

|I have decided to pass on the paint removal project as I am more afraid of destroying a perfectly good seat post just to try and remove it's color. I could buy the correct match post for $45 plus shipping, which I think is too much, or keep shopping for a post and use what I have until it shows up. I think I'm done polishing parts at this point, I just need to spend a little loot to finish the job of putting the parts together to get the thing on the road and then tackle frame finishing.|| |
