Wrinkly flat panels

Ok, a different offering?

Look around for some light weight sound deadening material.
It's right about 1/8" thick and either has a self stick backing
or can be stuck in place with probond.

(That's the way my neighbor did his 601-HDS anyway).

You really don't need to completely cover the area to reduce rattling.
A wide strip across the panel can be as effective.

Lastly, check that fire proof foam for "frangibility". (:^)

And how well it doesn't stick to bare aluminum?

You may find your fuselage is soon full of white fluff...

The stuff sticks amazingly well to almost anything. It is quite tough. I
guess if it started flaking off, I could cut a hole in the back and start sky
writing with the trail of white flakes.

Probably the premade dampening material would be most practical. I have used
them before. The better performing ones are almost as heavy as the foam,
though.

Certainly neater :^)

It really doesn't take that much material to damp the flat panel
rattling and oil canning.

If I'm not mistaken, this is the same kind of fire proof foam that was
used in the World Trade center to protect the steel structure from fire.
Too much was knocked loose during the impact.
The rest is history...

I'd expect the vibration (and expecially local vibratin (oil canning?))
would play hell with sprayed on foam...

So, have you started on the Zodiac yet?
