Speaking from experience, I cannot imagine anything that would out perform this product. It would be ideal for your application, as you could layer it on as thickly as you wish. It can also be easily cut to fit between the stiffening ribs. Also, very importatn, its properties do not evolve over time; in my case, four years later the stuff reamins just as gooey and squishy as when first applied.
In my original post I mentioned that manufacturer has a US distributor; I double checked and it seems they do not, but they do supply out of Mexico (very much in keeping with the global nature of your project... Russian conception, English drivers, Baltic birch, American carpentry, why not Spanish damping via Mexico?).
