Deforming object with spline and skin modifier- question

I have elongated object and I want to deform it (bend) using spine and skin modifier applied to object. And that's easy but when I delete spline, this object goes back to the original shape. How to make it permanent?

When you have it already deformed convert it to Editable Poly again. You'll loose control over it of course but I suppose that you don't need it
