Did you clear coat them?

No real need to with Aluminum, at least with a brushed finished (as opposed to polished).

nice, what did you use? ive done small things with steel wool before but that looks like it would take forever doing it that way.

I'd have used a bench grinder with a wire wheel :) .

I used an spray on oven cleaner, let the spray sit for 5 min, rinse off, and repeat until most of the paint camme off. Then i just sanded the cranks until it looked nice. I didnt clear coat it because i didnt have anything to clear coat with... but im prety sure i had read that i didnt need the clear coat for aluminum cranks

Interesting! How many repetitions did it require?

And no, Aluminum won't corrode beyond a thin, hazy layer on the surface. On a brushed finish, this can't be seen anyways. Only with a polished finish is either a layer of oil or a clearcoat required to prevent oxidation and the haziness.

If you get too heavy-handed stripping the finish (wire brush, sanding, etc.) you also quite probably take off the anodized layer, which immediately exposes the base metal to oxidation. Even with a brushed finish, they'll dull and look like hell in no time.

You should check out Khatfull's polishing threads in C&V. There is a lot of info about stripping anodizing, sanding, and later finishing. The temporary solution to prevent oxidation is a coat of wax.
