A "double cut" is exactly like it sounds. We have set up two large blasting cabinets. One has an abrasive media and the other has a very fine glass bead media. We hit the blades in both cabinets and the combination seems to close off the pores of the steel much better than just a single blast. This seems to offer better resistance to the elements.
