I finally found a product for the dash and other areas. The trouble with most is the extreme shine that reflects back like a mirror.
There used to be some products like Armour-All low sheen that had been a good option to prevent dash board glare but that does not seem to be out there any longer.
Found something for both leather and dash board called Eagle One Nano.
Here's a link. I used it and happy with the result.
