Two things cause our dashes to crack - both from exposure to the Sun. The first is that the ultraviolet rays dry the polymers out of the plastic covering on the dash. Thus the plastic becomes brittle and cracks easily. The second cause is the heat through the windshield expanding the dry/brittle plastic, then comes the night time when the plastic cools and shrinks, thus causing cracking because the material can no longer expand and contract.

So the best way is to recover the dash with a cover made by "Classic 9" (Made by Porsche owners for Porsche owners) - very reasonable prices for the quality.

There was a kit out a few years back that guaranteed good results with about 8 different small bottles of vinyl repair liquid - So you just filled and smoothed all of the cracks on the dash. The only problem with the kit was once the material cured the repair looked worse than before....

Once the dash is recovered always cover with a dash cover or a windshield sun screen when its sitting in the sun and not driven.
