How does it stick? Is it sticky-backed like Dynamat?

Yes, It is almost exactly like dynamat extreme except it is maybe a very tiny bit thiner. You just peel the back off of it and stick it on. It is extremely sticky. You have to be careful when putting it on because if you dont have it lined up proberly, it is very hard to unstick it. It conforms to bends extremely well. If you have ever used dynamat extreme, then it is pretty much exactly the same.
