Since we added power seat tracks and extra padding to my ‘63 wagon seats, my head is a lot closer to the roof, and in 90 degree heat, it’s hot. Anyone have a good suggestion on a heat barrier to put between the roof and headliner?
Lizard skin has a spray-on heat barrier. You would have to do some research to see how it compares to conventional insulation like fiberglass, rock wool, or the aluminized bubble wrap.
