I'm looking into what heat/sound barrier I want to use inside the cockpit. Does anyone have any recommendations (PN's would be helpful also)? Just looking at Summit's site, I'd maybe go with Dynamat 11101 or Thermo-tec 14620 (for a self adhesive type). I know I need to keep it thinner to avoid eating up space, but how low can you go? What's worked well for everyone?

Thanks!
Ben
