Thread: Rust under the rubber grip

So as the title suggests I found rust forming under the grip in my puma 63. I have unpinned it and can clean it up easily enough but was looking for suggestions as to how to seal the area to stop it from happening again.

Was also interested if anyone knows where to get new pins. It has one side that is already formed and is flat but needs the other side peened as normal. Pisc below.
