Just got new G37xS. Very attractive G37 logo embroidered in light color on black mat. Meaning in the Pacific NW here the embroidery threads will go dark and look lousy, impossible to clean soon. Any way to protect it? Perhaps some type of fabric waterproofing spray?

 

the way i preserve is put aftermarket mats on em. in that way, it never gets dull. you just might not see it once you put the other mat.

 

You can use 303 Fabric Guard to do exactly what you are asking. Just spray it on, let it dry, and boom you're good to go.

I use this to spray all carpeted areas in my car, but I also use rubber floormats as well. I think weathertech is the brand.
