How much do you think all of the material weighed? I would do this but I invariably end up fucking snapping some clip and then it eats at the back of my mind like a cancer.

About 43 Lb total weight added. Mostly from the MLV. As the name implies, it is Mass Loaded Vinyl, so it is heavy stuff. The breakdown in materials is on top of the string.
The key is judicial application of materials if you want to keep the weight down. The wheels/pavement contact generates the most noise, so I focused my attention at blocking off that source. The two front foot wells are right in line with the front wheels. The rear seat bottoms are right in line with the rear wheels. Rear seat back to block off anything coming from the trunk and doors to block sound reflected off of and emitting from other vehicles. No need for roof since nothing coming from there (usually).
As for snapped clips, I had the same phobia, but a pannel removal tool helped that:

Not a single broken clip.
