Tonight I wrapped up filling in the slots on the right foot shell with JB Weld on droid #2.
By now this should look pretty familiar. I applied a bunch of JB Weld to the slots with a toothpick.
And then I scraped up the excess with a razor blade.
I will do a some additional scraping of the dried JB Weld on all the edges, and then look the foot shells over for anything else that needs fixing before I prepare to paint them.
