I am trying to remove the black paint from an aluminum seat post I own. Does anyone know of a product that will remove this paint and NOT destroy or damage/melt the metal? Tried a stripping agent that did nothing.

Try "Goof Off". (Really!). It comes in a yellow can with red letters available at Home Depot. Worked for me.

Are you sure the black is not anodizing? If it is, the paint stripper will not touch it. I've never tried but oven cleaner is suppose to take off anodizing.

If the black is truely paint, you may have to go for some of that aircraft type paint stripper. An automotive paint store should have the good stuff. The Home Depot type stuff may not be strong enough.

Keep in mind that once you remove the paint/anodizing, the raw aluminum will corrode quite easily and get dull.

As already suggested, the seatpost is almost certainly anodized, in which case the "paint" is actually an oxide layer formed on the metal surface - strongly alkaline solutions will remove it (such as oven cleaner), but be careful or you will wreck the post - also note that this will reduce the diameter of the post a little bit, depending on the thickness of the anodization (so if it's a 27.2, it might end up being a 27.1)

If you use oven cleaner, be careful, and do a section at a time, rinsing very well afterwards - you will be left with a matte silver finish (will look grey) when done.
