I would go with powder coating the frame as well. Because while Powder coating the frame, the process of re- tempering, and annealing the fame happens at the same time. I would not sand blast the frame before powder coating, but I would use walnut shells. By using the crushed walnut shells, sand will not get into the small drilled holes that are in the frame from attaching various wires to the frame. Don't forget to file the welds before powder coating to look for faults in the older welds.
