Help design a test of heat rejection benefits of heat rejecting windshield tint.

I have applied this office/residential heat rejecting tint to my windshield. At 70% light transmissivity it should be legal in most jurisdictions, and anyway I can see through it excellently day and night.

Its maker claims it rejects about half the heat and nearly 100% of damaging UV light. I applied it imperfectly and need to do it again. But first, I think I will peel off half and do a side-by-side test of how well it rejects heat on my dashboard. Is there an affordable tool that you know to be good quality that I might buy to test with? Are there cheap hacks like melting wax in two cups on the dash, one under the tint and one not?

Thanks.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
