No; I'm talking about flexible, light (big bubbles) closed cell foam insulation, with adhesive on one side and a reflective (aluminum foil?) layer on the other.
ie: Something LIGHT!!! that you can stick to the roof liner, with a reflective surface reflecting any IR radiative heat back at the inner steel surface of rthe roof.

This kinda stuff.

LOL!
Well that's all up to you
But it's just the top surface, so not too much like your police cars.

A couple of people here have done white roofs and reported positively.
Not on black cars though!? IIRC
