Gentlemen:

I had the aergold on my previous plane and which it was very effective in reducing cockpit temps by 30 degrees F, the shape of the windows made it impossible for the installer to get it in place without bubbles, seams and other things which you would not want to see.

Short answer:  It works GREAT but is a bit unsightly.  I have decided NOT to use it on my new IVP.
