I have found that blasting is expensive and messy. I blast but don't dwell on it, just get the heavy rust off and then spray with muratic acid which makes the rest disappear. Then neutralize with a solution of baking soda and water. Let it dry and you are ready to prime. Be careful using muratic acid as it is nasty stuff. A good wiff and you won't have to trim your nose hairs for a while.
