you could paint your dash with aluminum color paint I did my old car a while back it came out good but when I clear coated it looked like silver maybe a autobody guy would know of paint to use, as for a shop to make a dash kit for your car i'm sure it will be big $$ and prob won't look good
Aluminum dash board? painting the dash board? I disagree with both. You are not worried about the aluminum heating up in the sun? I have seen aluminum floor board panels sold at local discount auto places. check pep boys!!
but if you want to talk about my car, let me know and I'll make an off topic or something.
Getting back on topic.
I really think that you will be pleased with TOUCHES of aluminum or silver in your car. IMHO When you paint everything it looks gawdy.... Like, painting the entire dash bezel, the guage bezel, shifter bezel, all one color, it just looks out of place.. If you just accent the dash you already have with a complementing color, the effect is MUCH nicer.
