I did everything including the hood and front fenders. Did the back half of the roof too, but ran out of time/ interest to do the front. Made a huge difference in ride quality. Feels more solid and is quieter on road. Didn't go overboard like some do, just made sure each panel had a decent piece on it.i see everyone sound proofing the doors. do you guys sound proof the roof? i did last year cause it rattles like a mutha.
