Another problem as I go on..

I'm in the process of refurbishing and getting to higher standards of my Lavi model.
I need help with the MeshSmooth.
When I do the meshsmooth the part looks good, but when I'm getting out of the MeshSmooth option the part returns to his original shape.
How do I save the MeshSmooth look?
