1991 300CE "restoration" is complete!!!
not sure, as I did not drive the car much before the "restoration".
But, it did reduce the noises from the trunk area, as in the slushing of the tank and tire noise from the rear. At least from what I can tell. If I had not taken the interior apart, I would not do it due cost and effort. Weight was not a factor for me.
awidiarto,
I had a body guy who used to come to my restaurant do it for $1,900 at a rented booth. He did a good job, not a $10,000 job but I am happy. He has since moved out of state.
