I lined the JK with Reflectix for now. In my 05 Unlimited, I used a foil backed insulation designed for firewalls. Glued it to 1/8 Luan panel with carpet like material on the other side. Also painted the very top part of the roof white.

I have a gallon of Bus-Kote waiting to be applied to the JK. Top needs to be cleaned, degreased and a primer applied first. Maybe soon....., it's getting cooler.

 

my driver side floor cooks my feet. anyone else notice this?

 

You rip your carpet out? Usually that will transmit some of the road heat up into the cab. If it's running hot with carpet, I'd take a gander under the tub.

 

The only change I made was to install hothead headliners on roof and around side windows. Of course I have the hard top.
