What kind of time do you estimate this to take? (Removal of interior, placement of mat, replacing interior)?
I've done this on restorations of old Datsuns, but never a "new" car.

Looks light as a feather or lighter. Great for anyone being careful with weight for weekend 1/4 mile runs, etc.. Fantastic to be light as a feather (execpt) for sound proofing.
Would be nice to also provide some instruction on adding some high mass (HEAVY) but not too much to the larger panels. NOT a criticism, just tell people to use a little heavy maybe Dynamat (Or generic for that) prior to the feathers and it would be hundreds of times better.
Looks like a good product to me, just attach a nice heavy mat prior.
