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

I made a little progress tearing down the LS430 today. Here it is before:





Here it is after:





The more I tear into it, the more I'm excited to convert things to manual operation. The grimy power steering system was especially making me feel this way.

The transmission has also arrived. I'm really excited about getting that installed.

Don't black-and-whites usually have the doors painted? Leave the doortops and do a panel the width of the windshield. It doesn't even have to be white.

That all comes much later, obviously.

Agreed! I have a lot to worry about before contemplating antireflective paint/vinyl wrap... I need to make this thing run first.. It will be getting undefined MPG and have zero value sitting in the garage doing nothing.
