You intend to spray foam on the underside of the poptop? 
I just sprayed the garage. 1800 sq ft of that stuff. 
It'll be interesting to see how it comes out. 
Getting a "presentable" even finish will be a challenge.
Having experienced the heat-stopping results of the foam on the sunny
side of my steel garage walls, I would expect excellent results in
blocking the suns heat in summer and keeping heat in, in winter
