I have a 1983 e28 which, until a few years ago, had a perfect crack-free dashboard. It is garaged all the time and when parked outside I always use a sun-shield. It has done no good and the cracks are appearing.
Is there anything I can do to repair (fill?) them or prevent them expanding?. I am guessing not.
I don't like the idea of a dash cap, but perhaps someone can recommend where I could source a high-quality dash mat?
