Dash Preservation

[IMFletch@aol.com]

Fellow MG'ers,
   I am recovering a dash from a '70 GT for my '69 B. The dash is in fairly
good shape and will look much better with a cap installed than my existing
dash. My question is: what's the best way to make a dash last? The material
seems to remain dry and unpliable (i.e. just waiting to crack) no matter what
I've tried. I've mostly used Armor 
All or a similar product. One friend suggests using saddle soap. What have
you found that works best?
