Hello group! I got a 2017 Honda Civic LX sedan and loving it so far! I really want to take great care of it so it will last. I was needing to know what to use to prevent sun fading of the fabric interior. I guess sort of a 'sunblock' for auto interior. I have the expandable car shade for my front windshield. I'm needing something particularly for the back seats fabric headrests. they look very vulnerable to sun damage when i park. when I'm home it is in a garage. thanks :-)
