does anyone know how many sq ft is needed to do the doors, floor and trunk? is 100 sq ft plenty?

 

Should be plenty if you know what you are doing, and don't waste a lot of it.

 

oh ok thanks alot

 

Wow the whole car, 100 square feet how many pounds is that goin to add?

 

^^ its the same before you install it, just add the lbs.

 

30-40 lbs depending on the material. I was going to do this and decided against it. Has anyone done this and felt like it ruined the spirit of the car? I was really afraid of making it sound dead like a lexus. My Mazda 6 has absolutely zero engine noise and it's... boring.
