Euro light stone guard

[rbade12 at aol.com]

 I presently have stone guard on my euro lens, however, it's a bit old and not sticking well. I've clear silicone glued it in places to keep it intact but I'd like to replace it with new if possible. I've had no luck finding a source for new. Anyone know of a source? I've thought about, once winter recedes, to take the old off, remove the old stick-um and re-glue them.
