Electrical tape works great for protecting bearing surfaces that you do not want blasted. Use 3 layers and you will have to actually try to get through it to blast it off.
Electrical tape is soft enough that the sand just bounces off it. Glass Bead will help as it is less agressive than sand. But it is not good for removing scaly rust. Matthew
