Sodablasting does an excellent job of removing paint, not so good on rust. walnut shell is not much better and is a bitch to clean up.

61Bone, i just seen where you live and i am in your neck of the woods. do you know off the top of your head if Sturdevants or ABS in Sioux Falls carries soda for blasting media,i guess i can call them too.
