You want to use the least aggressive media that will work, and that will depend on the type and condition of the paint. If you can find a supplier of 'metal finishing' products, get samples of several media and try them out.
But are you sure you want to blast? The bounce-back and overspray can damage anything in the area that isn't well masked. Plus the dust gets everywhere, and is probably loaded with toxic nasties. I'd try chemical paint strippers first.
