I am going to pull out all my seats and carpet in the car to dynomat it and was wondering if it was glued down, or if i just pulled it all up dynomated and then put it back on it will look like it does now. any tips on this please tell

 

Carpet is usually held in place with a combination of christmas tree fasteners and other trim pieces.

 

Ditto. An, if you bust the fasterners, you can get them at any parts store. They arent anything special.
