Does anyone make a 'heat shield' dash mat?
 

Just replaced the leather dash in my '86 turbo.
I'd like to find a dash mat that actually keeps the sun/heat off of the new leather. Maybe with a reflective foil under the cover?
Will I have to settle for a full windscreen cover with reflective material - like Coverking?

I believe just a regular dash mat would work just fine, maybe a lighter color than black. Think you just want to avoid direct sunlight on the dash. It’s really hard on the leather
Good luck

If you need to leave it parked out in the sun the reflective windshield screens will lower the inside temperature of the whole car as well.

I actually like the Cover King better. Keeps the whole car just a bit cooler. Of course I don’t leave the car outside, except for short periods, like an hour and a half tops…

You might be able to find a local shop that will put a clear tint film on the inside of your windshield - this will keep a lot of UV light off the dash. I had this done to all windows save the windshield on my Saab 900 - too much curvature in the windshield to be confident putting film on it
