I bought an accordion sunshade on Amazon way before I got my car. After I got it, I looked at the reviews on Amazon for some reason and saw one that said it scratched up their dashboard. They included a picture and it looked bad. So, I haven't used my sunshade yet as I'm too frightened to scratch stuff up. I'm in Texas, too.
I'm a bit scared of the Armor All since I used one of the wipes at the bottom of my door (I always kick and scrape my damn car door when I get in and out) and it left a film. It eventually wiped off, though. As someone mentioned above, it would have been better if I didn't just wipe one spot and did the whole thing instead.
We all should have a meet-up where we scratch each others' cars so we can get over this madness!
