Dynamat

Does the Lowe's stuff have a strong odor? That's what I read about it... that it smells strongly like tar and the smell doesn't go away. Whereas the Dynamat and similar are made from butyl rubber which only has a faint rubber smell that goes away.

True story? If NOT, what is this Lowe's material called specifically?

Eastwood right now has their Thermocoustic on sale right now for $20/5sq.ft.
