no, chunks of the zinc were still stuck to the sides of the hole.
I thought I had pushed the whole zinc in, but turned out it was just a piece of it. it just kind of was crumbly.
I was trying to put the plug in from the top so I wasn't looking at the hole, when I realized it still wouldn't go in.
looked and found it was still blocked by the zinc, even after all that water poured. out.
so I had to use the punch to knock the rest back in along the sizes of the hole.
