DIY Lizzard Skin
I sprayed Lizard skin on my underside and then mixed those same micro-spheres into my single stage urethane activated paint when i did the bottom side of my car. Haven't driven it yet so can't say how well it all works but I'm hoping to keep it as comfortable inside as possible. I also used sound deadener mat inside the car along with another layer of lightweight heat insulator padding before installing the carpeting.
