I don't know if there a sponsor, I'd assume not since i've never herd of them here, so I won't link it. It's a spray on sound deadener made by Cascade (hope that's okay to name it) that I'm considering buying. I know it's not likely as good as the other stuff, but I'm more focused on stopping plastic panels from rattling than road noise. I was thinking about just useing it for the sail panels and maybe the doors.

Anyone use this stuff before? If so, did it help any?

 

If your going to use spray on deadener you can use something as simple as Flex Seal....as seen on TV. Its just as good...liquid rubber in a can. That won't help panels keep from rattling though. They rattle because they are loose fitting. It might help some panels but most of them it won't. For example the rear hatch panels are only attached on the top and nothing on the bottom so they will always rattle with the right amount of force. They just lay on top of the carpet.
