TIM... I use NVH foam - noise vibration harmonics -
I sectioned in 3 layers of metal... the wiper cowl bowl rear lip - the wiper cowl top (where the wiper towers attach and then the dash top) then the front edge of the dash top.
I am not worried about water penetration on restored cars, the additional sealers and the care taken of the cars all but alleviates the possibility -given that the correct sealers etc are used.
I also coated all of the metal with ZINC rich primer and then weld thru primer.
In this photo you can see the edge of the lip on the speaker grille that Bruce was speaking of...
