Yeah, I did in my CX hatch this weekend. It helps a bit. I just did it on the rear floor area, not inside the doors or anything. It seems to make a big difference below 60mph, but above that it's still loud as hell. Highway speeds are just this constant howling. It sucks. I also pulled off the rear interior panels and sprayed the metal behind them with underbody coating.
Did you spray any on the wheel wells? Seems like that's where most of the noise would come from. And do you notice any weird smells?
