I took these cranks:
And made them look like this:
I feel good haha
Did you clear coat them?
No real need to with Aluminum, at least with a brushed finished (as opposed to polished).

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.
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.
