Heat and Vibration deadening products questions

[Pinguino]

Is anyone using Second Skin or any other product for the heat / vibration in there cars? If so give me some sort of a run down on the best one out there Vs the price.
Here is a package price for one from Second Skin for FFR. It is A-lot cheaper than Dinamat and boast the same results.

For my FFR build, I used LizardSkin spray-on insulation over the complete interior, an additional layer of Dynamat on the trans tunnel, and carpet over all. I'm very pleased with the results. The LizardSkin products I think are pretty cost effective.

If you search, there is a how-to replicate lizard skin using stryrofoam balls you get at Hobby shops and paint at fraction of the cost.
