Nothing. This is the problem with foam. It will eventually dry, then crack, then fall apart.

Start shopping for a new sub. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Why do expensive subs use foam instead of rubber?

Because foam is lighter, and more efficient (usually).
