UCA BUSHING REMOVAL/BALL JOINT BOOT QUESTION

Good idea, I kinda hammered my all thread piece, went back to the bolt cause it's grade 8. Drove the outer shell out with air hammer. Thanks for all the tips everyone. Now that I've got the arm stripped down, I'm wondering best way to clean it up. Thinking about media blasting it but guessing powder coat is not a good idea because of ball joint threads?IMG_1244.JPG
