Review on High Tensile Strength Duct Tape Silver, 5.8mils, 2 Inches x 50 Yards - All-Weather Duct Repair Tape for Commercial Use, Heavy-Duty Repair, Packing with Temperature and Shear Stress Resistance - XFasten by Michael Reese

At first I absolutely HATED this tape. It's really thin, NEVER tears straight (constantly gets runners and foldovers), and doesn't stay in high-heat/high-humidity applications. I bought it to seal the edges of my window-mounted exhaust from the 2 "portable" AC units I have to run in NOVA summers.However, the fact that it holds reasonably well but leaves ZERO residue has me here buying another roll! It's excellent for taping window tint panels to the windowsills. Seals just fine in this application, stays in place, and again, when winter comes and I remove the panels (to let the sunlight/heat back in), there will be nothing left on the sills! The gorilla tape I used last year was way heavier, but it left a TON of black gunk all over the place.
