Anodising external BB cranks is a world of trouble, because the acid bath isn't kind to the pressed in steel axles or the glue that often accompanies the press fit. Also, my machinist reckons JB aren't all that, Metro in Uxbridge are better.
Those cranks look painted anyway, so laborious mechanical removal of the paint should get you back to raw aluminium without the risks inherent in media blasting or chemical attacks.
The reason I suggested buying new is that every other option is labour intensive; either a lot of hard hand work, or some costly masking operations to protect the axle, threads, splines etc from a more full-on attack.
