Hi,
Restoring a rusty car will be a never ending and very expensive effort and the (probably never) finished project will never be worth anywere near what was spent on it.
I would suggest cutting your losses and buying a good rust free CA car and keeping yours for parts. You could buy another for far less than you will spend on restoring yours. Just my 2cents.
Best wishes on your project,
Tony
