What else is needed? (ah, I see the answer below)

A sign for the yard that says Frank's Tire Repairs?

Actually, I think I have all the necessary tools but this one:

Having used the hand scraper and the wire brush, I see that it would be a
*lot* easier to use these "buffing cones" because the shape of those cones
would better conform to the shape of the inside of the wheel.

So the advice I give to anyone reading this thread in the future to assist
them in doing the repair is to get one of those buffing cones.

You won't find them in a typical hardware store though, I don't think (at
least I didn't).
