Masterpiece Megatron is notorious for two problems: impossible transformation and tarnishing of metal parts affectionately called "cosmic rust." The first problem was easily fixed. I transformed him into robot mode and left him that way. The second problem was actually not too difficult to fix either. I found some old Mothers Mag and Alumminum Polish in my closet and used some of it to polish up the right side of Megatron's right foot. Here is the before picture: And after: You do have to be very gentle so the chrome doesn't wear off but it is cleanable. I'm curious to see how long this will last. When I buy more I'll have to finish the job.
