I think I'm going to get the rattle pad and apply luxury liner on top of it. http://www.secondskinaudio.com/cgi-b....cgi?pg=4&p=ps
The rattle pad weighs almost nothing all together and the luxury liner is about 1 pound per square foot so I figure it wouldn't add more than 45 pounds to my car all together.
I'll probably be doing this on thanksgiving break since I'll have more than one day to do it then. It can be done in an all day session but I wan't to take my time and do it right.
Thanks for all the advice.
