I think the ink is protecting the copper rather than etching it. I've used Sharpie to label tin cans which have eventually gone rusty because they're kept in a damp shed. The last bit of tinplate to...

Looks like a pretty stiff, well stretched dent. Trying to pull it out might cause more damage to the panel.

Welcome, Mike.

If you want old-school, I don't think you can do better than reading up on boat lofting. The techniques are directly applicable to buck making.
