HEY! I know you!!!
(just kidding, but maybe. I've lived in Canberra a couple times...)
I prefer scraping the binding to clean it up rather than any other method (like sanding).paint was dry enough to unmask the binding. It needs some minor tidying but overall looks good to me.
If you haven't already done it, a DIY binding scraper tool is easy to make.
Mine is pretty much like the one in this pic:
btw, not my pic or tool. I just pinched it off the interwebs.

You might know me if you worked for CSIRO. Or if you were part of the Canberra single-speed cycling thing back in 2011 or so.
For the binding, I have been scraping as needed using an exacto knife. I like the precise depth control that your widget offers, that would make things a lot faster.
