I am scratching my head on this one. I have a 90mm RB67 lens that I have torn apart to rebuild. I have done 3 of these lenses and shutters with no problems. This new one has a 2 pinholes on one of the metal shutter leaves. Does anyone have any ideas other than tearing down the the shutter and swapping the leaf out, for patching the hole. A friend mentioned to me to use a pinprick of JB Weld, while compressing from the other side with wax paper.
I thought of micro soldering to plug the hole.
I also might patch it with that really thin self stick aluminum metal tape.
I might even just use some thick super glue and quick bond agent to freeze it in place and then color it with a permanent black marker.
Anyone have any other ideas, for this predicament?
I do have another lens I can swap out the blade, but wanted to keep the shutter intact if I can.

Wow, how on earth did that get there? Corrosion?
The suggestion of opaque epoxy is pretty good, if you carefully scrape the repair flush with the leaf, it should work.
