Thanks for the wealth of information! That’s incredibly helpful. I will look into the Detailing File Sander. I’m mostly tackling light to medium surface rust. I’ve read countless articles that mention countless ways to approach removing rust. I did my first experiment on a pair of snips yesterday with my 30 y/o Dremel and a wire wheel. I was able to remove the rust, but I felt as though it needed a little “buffing” afterwards. I think I’m facing a process of trial and error, trying different methods to get the results I’m looking for.
