I have been using duct tape for a while now in various odd applications. I think that if a repair can be done in any way other than using duct tape, it should. But duct tape has an exceptional strength and useful life span, along with its durability. I always carry around papers in my pockets. It started out as just a 8.5X11 sheet used to jot stuff down carried in my right side pocket. But I fast found that I had to replace the paper every few days. That meant copying everything over on to a new sheet every week. I got tired of that fast. So, I spied a roll of duct tape laying around. I picked it up and started wrapping it sticky side out around a stack of 8.5X11 sheets quarter folded. Got it done. Now I had a sticky pouch. So, I covered the whole thing shiney side out. Now I had a strong pouch perfect for holding my papers. It would hold up to the wears and tears of my pocket and protect my documents. It became known as my document portfolio. I liked the way it performed, so I made another for my pens. And another for my deck of cards. And another for another deck of cards. Soon the word spread and I was making various stuff for people all over school. Now I made my document portfolio four years ago, and it is just now needing a remake. A couple of years ago it required some patching, but I was impressed with the durability. I had become so accustomed to my use for the shiney substance that I forgot its true purpose. I had some ducting to do, and I forgot you were supposed to use duct tape. But I was reminded, and it did a pretty good job at its intended purpose. I haven't used it to hold doors on a car, or anything else like that, but it is pretty dang good at protecting stuff.
