Ultrasuede® Seat and Door Inset Protection?
 

I suspect being Japanese that this brand of faux suede is Ultrasuede® as it a Japanese product. What are people using to protect this fabric? Has anyone sprayed any fabric protector on the gray suede? If so, what did you use and did it affect the color?

Thinking about using Stoner's Fabprotex, but with spray can in hand I hesitated as I want to learn whether anyone else has already done this (read, screwed-up their suede)?
