Do not use ANY silicone based product on anything in your car. When the product dries up, the silicon starts to shrink and can, eventually, dry out your dash and crack.
Only use a non-silicone, UV protectant, product just ask your car accessories supplier.
PS: Hey Jayson, How have you been? I am trying to get my car back together b4 the interstate meet up in May, so hopefully we could catch up then.
