Build-a-dash!

I've never used the crackle paint myself, so I'm just sayin', but they make it for engine parts, so it should be pretty durable and heat resistant. Your biggest concern as far as paint will be UV resistance. Another thing you could try is roll-on bed liner, not spray-on-in-a-can (that stuff doesn't really have texture). I did the interior of my farm truck with roll-on bedliner (except for the dash and dash-pad). It looks good there aganst the new grey door panels, new grey upholstry and new grey carpet, but hurts a little when I rest my arm on the window opening. Im not sure how it would look on the dash, might be great, might be absolute crap, just a thought.
