How do I fix that classic Dashboard Crack?

Is there a method for successfully filling in or cosmetically repairing that classic crack that always goes right down the middle of the dash? Can it be filled with some sort of caulking and then sealed? The rest of the dash is in perfect shape and getting a new one is too damn expensive. Anyone fix this crack successfully?

I had a few cracks in my 911 dash which I repaired with reasonable success. I got a filler and the dye to match the dash from Larry Reynolds at Car Care Specialties in northern NJ. I believe it is called Surflex. The number is 201 796-8300. He may have an 800# but I can't find it. He will give you a short lesson over the phone.
