I can get 100ft of that tar tape stuff for like I dunno 10 bucks or so I'd reckon. I need to check into that.
There are two differences:
1) adhesive
2) thickness
It's an asphalt/tar based product, but that's not really a downside - it functions as a dampening product, absorbing vibratory energy.
I've heard some people complain that the adhesive is so weak that it falls off the door, and other people say that theirs works fine. Both those pictures that people posted look like they are very solidly on there, no adhesive problems. Of course, with any damping material, installation technique is critical - see how well both of those are installed in those pictures? Very good.
Some people half-heartedly stick their damping material on, leaving voids between the adhesive and the door... they don't use heat, they don't use rollers or push-sticks, and the result is poor adhesion, or poor longetivity - it's tough to say whether a failure is due to the adhesive or the install technique, but surely a superior "intended for a car" adhesive would help.
Also, the thickness of the material might help. One thick layer is as good as two thin layers, and removes layers of opportunity for adhesive failure.
If you are using it to span holes in a door cavity to create a functional "speaker enclosure" out of your door, it also helps - three layers of thick, true automotive grade damping material product can be pretty rigid and contain sound, where "peel and seal" product isn't going to perform as well - unless you literally layer up five or six layers in that same span.
Personally, I'd rather go for one of the more budget-friendly automotive-intended products over hardware-store products meant for gutters and shingles in a completely different application. I've used Second Skin personally, pretty extensively in two of my vehicles (I bought a huge roll of the old STFU-80 - similar to "Dynamat Extreme", and had good luck with it. Buying the huge bulk roll was also more budget-friendly, given how much I bought (I still have some, as a matter of fact!).
