My irons are satin black.....

[15 Handicap]

Is there a paint pen/way to fill in missing black finish from bag chatter?

I am not sure, and have never tried, but wonder if something like an automotive paint pen might be your best option?

I hate to say it but,,,,,,,kak, gug! Iron covers!

Some gun blue might also work if the chatter form the scratches that got past the finish
