how to polish old aluminum parts?DougSloan

I tried to polish my 23 year old aluminum seatpost, and just made a real mess of it. It now looks dull gray. I used polishing compound and a buffing wheel on my grinder. I'd not only like to fix it, if possible, but touch up the crankset and rings without making them worse. Any hints? Thanks.

I assume they still make it--haven't seen it in years, but I think I saw an ad a few months ago. Comes in a little tube that costs way too much, but it works.
thanks; I'll check an auto parts store nmDougSloan

Check out your local Harley-Davidson dealer...they sell Simichrome.
Simichrome or Mother's chrome polish. Both are great nmDave Hickey

simichrome is the best. antique stores will have it. also buy some 000 or 0000 steel wool from a paint store. applying the simichrome with the steel wool will really bring out the shine. just did some old high flange Campy hubs and you can shave in them.
thanks. i'll post a pic of before and after nmDougSloan

An old "Bicycling" mag article (back when they were good) suggested polishing with jeweler's rouge, or cheap toothpaste. Don't know where to get the former, and never tried the latter, but it does polish enamel, sort of.
