'Cause I need a wheel with a very large diameter AND narrow tread AND a

The tin I worked with had a _center_ nail or two. I thought that was
what you were looking to remove. Perimeters are mucho easier (but
still a major pain.)

Satanley makes a mini wonder bar which I use to get into small spaces.
It's made of tough spring steel, about 5" long, 1/2" wide, maybe 3/32"
thick, with a 1" long pry head. This is your best bet.

I grind the curved end of my HF multipurpose pry bars thin on the belt

Then again, tin is easily beat back into shape on the edges. Stock up
on repousse hammers and make wooden dies for the edge shapes with a
dremel and tubafore if necessary.

I'd also use a scribe to remove the paint from that joint so you can
see the edge you're after a bit more clearly.
