Opinions needed on removing rust, underside of hood.

The center of the hood of course is not a problem, I can get a wire wheel to that. My dilemma is the rust underneath the supports.
I have been reading about rust removal methods.
One method using the Muriatic Acid bath. Another method using the Electrolytic Derusting, where you use a mild electrolyte and a battery charger, which is'nt really suitable for an item this large, as far as I can figure out.

I would really appreciate your opinions on how to go about this, I really don't know which way to turn.

Replacement is not an option, the hoods in the boneyards are worse than this one, shipping is to high for one on ebay.

Just to give you the whole picture, the top side of the hood is fine, I have already sanded it down to bare metal like the rest of the car and primed it.

Here's the pic.

That hood looks almost like a car fire hood, Ever have an engine torch under it?

I was kinda thinking the same thing the way it's concentrated in the center then expands out. I don't know though, I've only had the car 6 months, only started it a couple of times, I've been restoring it since I got it, one area at a time.
The hood is straight though no warpage, so if it was a fire, it did'nt get to hot.
Will sandblasting be able to get in under the braces?
