Was just cleaning up my garage tonight since it's going to be 70º here in PA tomorrow and figured it would be a great day to detail my new 2019 RAM 1500. Just organized my polishing pads and cleaned some that looked dirty, and figured I'd take the backing plate off my 3401 and make sure all looked good since I hadn't used it since the fall. When I took the plate off, I was horrified to see that the counterweight is covered in rust! I don't remember noticing this before, and I definitely have not gotten the inside of my machine wet. Does it need to be replaced? (the counterweight that is). Picture attached....any thoughts?
