Since I have an 86, I figure this is not off-topic.

I volunteer at a non-profit Yoga studio and money is tight there. We desperately need to put some heat-blocking window film up in a few places. I'm not sure if we are going to do the install ourselves or not, but I know from some limited car experience install on a flat pane of glass should be easy-ish.

I'm sure there is someone here who can tell me what I should be looking for and perhaps name a few good brands of window film. Heat rejection is the most important consideration.

Thanks!
