Misc. Heat barrier for hardtop ?

[Rustkill]

Hi. Has anyone use radiant heat barrier paint? On the inside of the hardtop to help with heat ?
Or what would be a good option to help with the heat and to help the ac work better. But still keeping it looking good
I was looking at lizard paint. I think it’s called
But also saw other easier to use radiant heat paints.
I know nothing will be prefect but anything that can maybe knock the heat down 20 / 30 percent would be nice

?? Thanks.

I cannot actually reply because you said with your air-conditioning.
If I was to say any of the paints.

Well I mean I will have the ac running and maybe a paint on the hard top would help block some radiant heat so the ac does not work as hard.
Maybe it would help keep it a little cooler on the inside
