I would use Rage Gold to get the bulk of the low, if you would even need the metal glaze you could use it for pinholes and minor lowspots. But you said it's pretty straight now so it's tough to say if you would even need it. Good thing to do is just get it roughed in as good as you can, then go ahead and build a few thick coats of primer and block it out to see what you have. That's how I would do it.
