OK, I looked over many threads on fatmat/dynamat etc. I can get Fatmat at a good price in Europe, and it seems it is slightly better than dynamat. But before all that..What I want to know is, SHOULD I do this or not? How far do I go if I do, what happens to entering my car to shows etc.? Will it be marked down for having it? I love the idea, especially since I drive my car as mush as possible in the summer. Making it quieter would be a really good thing. I know my wife would like it more if it was quieter when riding in it to shows etc. But, I am torn between doing it and keeping my car as close as possible to stock. I am sure others have debated this, so I would love to hear what tipped the scales in either direction for you all.
