I have about 1 sq.ft. of dynamat extreme on flat surfaces in my trunklid and probably 10 sq.ft. of some random cheapo stuff from a hardware store plastered over the entire thing. I've noticed that the cheap stuff peels off in heat or just over time. However, the dynamat extreme is still holding tight. Which of the cheaper alternatives (RAAMmat, Peel-n-Seal, etc.) sticks best to the trunklid, including the curves? Im thinking of spraying the foam stuff into all the openings where my hands cant reach but i want to put some stuff like dynamat over the rest of it.

 

I've used V-Blok, with excellent results. But then again, some of it is spray-on, and some of it is stick on.
