Jim,
I am doing the dash in black ultrasuede. I had considered Alcontara which is very similar, but it is not carried in the US for some reason. I am using this to avoid any reflectivity off of the dash and because of the qualities of the material you mentioned.
I had considered making wider use of the ultrasuede, but decided not use it because of cost considerations. I will be using a high quality cut loop automotive carpet instead.
Regards,
Lynn
