Acetone should take the paint off, as usual it depends on the type of paint.
Thinners would probably work too. Try it and see, you have an advantage as
the paint is still fresh so it won't take too much effort, especially if you
mask off where the laser won't go.
Paint strippers won't damage the metal, they're solvents, not acids. That
citrus stuff works well.
