I recently acquired a used protech. Mechanically it's flawless but the blade itself has a lot of surface scratching. The pivot and clip were pretty scratched so I just buffed them out and bronzed them but thats not an option for the blade. I need to preserve the blade coating it's a big reason why I got it. I'm a sucker for FDE/OD green. These scratches DO NOT go through to the bare metal so I'm thinking about using some brasso on a rag OR maybe some finishing polishing buffing compound??? If you have experience with this issue and there is a better way to get these surface scratches out I would REALLY appreciate your feedback!!!
