Not worth investing any money in an old tank.

I would strongly suggest a new tank. The standard warranty with tanks are 6, 9, and 12 years. I replaced 2 in the last few years that were each 12 years old. One was leaking and the other was rusted on the bottom waiting to leak. You are going to have to replace soon so I would suggest now before they start leaking. 

I replaced with GE which are made for them by Rheem. Purchased at Home Depot.
