If the plan is indeed to replace the foam (and I kind of prefer that
myself, since it keeps the machine more like it was when originally put
together), you could consider replacing it with ethafoam. It doesn't have
the breakdown problems of regular foam - in fact, it's archivally safe for
museum uses - and you can get it in a variety of sheet forms, including
anti-static versions.
