They both work, but in 2 VERY different ways. typically speaking, the spray is designed to transfer the vibrations into low grade heat. The mat is designed as a "mass loading" mat, which lowers the resonant frequency of the panel. Foams are typically designed to absorb noise. What works best? A combination of all of them. What is most expensive? A combination of all of them. I would suggest staying from the Home Depot/Lowes/home improvement store solutions. These are typically designed as underlayment for roofing.....its a flat surface. Typically, these are pretty thin; the adhesive is marginal, at best; harden over time; and are not designed for automotive use. Just because its a cheap tire, does not mean a bike tire will work well on your car. Depending on your climate, the home improvement stuff will become brittle in the winter (below freezing), harden over time, and fall off.

Got a bit of help earlier this week removing some of the gasketing as well...

A few more parts came in over the past few days. A few chrome bits and some gaskets. Then these:

The interior and the motor as they were when I got the car. It came with an L28 from the previous owner. Brake lines went on as soon as I got the car home. The Z does not stop anywhere as good as my VW Passat....that will change in the future

A little introduction: My dad and I bought a 1972 240Z in late July 2012. He was retiring from 35 years in the Army, as well as 13 years after that. It was to be a Grandfather (him), father (me) and son (Ryker) project. When I was younger, my dad had a 280x 2+2. So, I knew we liked the car. I wanted a 1972, as that was the year I was born. This particular car was the 1st one we looked at, and we bought it within 24 hours of test driving it. The previous owner had repainted it the factory orange, but it is a pretty poor paint job. That's ok. He did, however put in a L28. A little extra for the 240z.... Unfortunately, My Dad passed away in early August. We had only made a few plans for the car. I wanted to change the motor. He wanted to keep the L28. We are keeping the L28....but will add a turbo. My son, Ryker, 5, has named the car Roz, from the movie Monsters University. Now, onto the madness.
