How do you fix a waterlogged galvanized well water pressure tank?

You let it totally empty with pump OFF, then with valve to service closed, you switch pump ON till water comes to level of service pipe (usually about 1/10 full. ) Now switch pump off and fill the tank with 28 psi of air. Now it is no longer waterlogged.
