Dash preservation

Greetings,
I recently aquired an 88 coupe with (well documented) 14,000 miles. The dash is in excellent condition but I would like to give it some life and protect it. I have read all the adds but what is the advice on a product to use as a presertive? What is the advice from those corvette owners that have been doing this for much longer than I?
Thanks

I've always just used good ol' Armor All and never had a problem. I had a T-Bird Supercoupe in 91 that I started using that STP stuff on (green bottle) and had cracks before the car was 3 years old (of course I was in Alabama at the time) so I've gone back to the product that I've never had an issue with. I'm sure there's some specialty shops that sell some good stuff, but I'm wary of change now.

Thank you for the advice, it has been most helpful.

i also use armor all, and i keep a sunscreen in my car...
