Bill, thanks for using metal roofing and more importantly wanting to verify that you are receiving the best quality. The only way I am familiar with this is to send a sample to a lab. Have you asked the manufacturer to confirm that Kynar 500 was supplied? I am sure any of the paint companies that are members of the Metal Roofing Alliance would be willing to preform the test.

Is there a any way to verify that Kynar 500 is used in the materials delivered at site? I just want to know I'm getting what I'm paying for and not receiving a short-lived topical paint.
