Hey Spec, that is really nice of you to offer this, but I am actually very happy with the Reynolds heavy duty aluminum foil. I have to different rolls of HVAC duct foil that I am going to try to see how it does but, I don't think either one is as shiny as the Reynolds and I don't think that the scales will stand/press out as well because of the thickness of the glue backing. will let you know how they turn out if I ever find them. Again, thanks for the offer. John
