Any experience with Z-mat for sound deadening & thermal insulation?

we've got a 66 bronco torn apart and will tackle sound deadening & thermal insulation. Has anyone ever used Z-mat? Looking at Dynamat Extreme as another option. This would be on the floor, doors, quarters, tailgate, hardtop.

I didn't use Zmat but i did use a sound deadener. Honestly not sure it makes a big difference for noise. I seam sealed first. Keeping the metal dry is important.

I used dynamatt forget which version, the gooy one side alumin foil the other. Thats all they really had 15 years ago. Also dynamatt/pad or some soft foam like stuff, no adhesive on it so thats under floor. behind firewall to seast.. And Bed liner really does help sound and heat.

I did not do doors, they still need tweaking. nothing on quarters other than bedliner and accmatt carpet. Tailgate I sound proofed it by using hosing around anything that moved, then a few sheets of dyna. Hardtop is all dynamatt and that crappy cardboard liner.

I also used dynamatt off firewall, along with hi temp reflective aluminum, then finished with Wild Horse firewall insulation kit. No heat felt on that anywhere.

I wrapped exhaust pipe, not headers, from behind header to muffler. You can almost touch the wrap with engine on, almost.

You cannot feel heat up from floor at transmission.

I used this on floors, quarters, inside doors. It helped with noise and misc rattling. Good price. IMG_1719.png
