Different Kinds of Duct Tape
I prefer the foil (think heavy duty aluminium foil) duct tape rather than the cloth-backed duct tape.
The foil tape is bright and shiny like aluminum foil. It's readily available for extreme temperatures and conditions. I've used it successfully in several applications exposed with outdoors - sun, wind, rain, snow - and it holds up for years. I've even used this type of tape to create semi-structural elements. For instance, when I needed a fan plenum for an electronic module I was working on I simply used several layers of the foil tape and was able to create a metal box that I attached the fan to and it worked great.
On the other hand, the cloth-backed duct tape does not last nearly as long and it does not hold up well outdoors or under extreme environments. In addition, when it fails it always seems to leave a gooey, very messy residue behind.
The picture on the left is tradtional cloth-backed duct tape. The picture on the right is foil-backed duct tape. The foil tape has a separate release liner so it's easy to cut to length, peel off the liner, then apply it to the surface.
