With a badly cracked dash, what are people doing besides throwing a mat over it? I've seen leather and alcantara re-covers, but in most cases those are done on a dash that isn't in bad condition, since cracks usually show through since the surface isn't flat like it should be. How about some crazy ideas like filling and sanding flat, then using a coating similar to a bed liner? something with a slight texture but able to fill imperfections. Anyone try anything unconventional with success?
