Yeah, you just put your car on a lift, or jackstands, but the lift is much better for this, and then spray like 2 coats on the exterior sheetmetal of the trunk and rear wheel wells.Make sure you get it nice and thick behind the muffler heat sheild. I did the whole floor pan and my car is as quiet as a BMW. Like Jason says, their carpet padding also works good and when added with the liquid, it should get really quiet . It will also make your stereo that much louder too!
