Quality product, pricy, but worth every penny. I had multiple air bleed connecting seams, did my entire basement ductwork with 100 feet and some left over to do a few more seams. Get some little scissors to cut it with, makes life easier. The utility blade crumples the corners a bit, which makes it trickier to get the backing off. Hope this helps! Review: Great price for how much you get. Very sticky. Easy to use. I use on my hvac registers after cleaning them up. Keeps attic air out. Seems like quality product. Very strong.
