Sound deadning reviews

I am almost ready to put some sound and heat deadening and have looked into the lizard skin products. I think they will do a great job at controlling the sound and heat. Living in Texas I am really looking forward to reducing the heat that comes from the roof of the car. The good part is you can paint over it if you want to do the outside firewall, you just sand and apply body filler and it gives a smooth finish and stops the heat from the outside and then you can also spray the inside for the added protection from the heat and sound.

Kinda expensive but I think it will be worth it in the long run.
