My best guesses here - duct/duck/ gaff tape; form least quality to best
1. dollar store duct
2. common silver duct tape; Target, Lowes, etc.
3. Gorilla branded tape
4. Gaff / gaffers tape (used by stage hands)
5. 100 mph tape
Your opinion?
There are many, many grades of duct tape that are silver, from the cheap stuff to some very good and very expensive versions from 3M, Nashua and others. Some of the specialty types are designed for greater adhesion or more or less resistance to tearing, etc. There's one for whatever ails you. :-)
Gaffer Tape has the advantage of easy removal, but isn't all that great for adhesion and just as with standard duct tape, there's better and worse tapes all labeled as Gaffer Tape.
So-called 100 MPH tape doesn't exist, per se. It was a slang term that was grabbed hold of by some marketing types, and you know how that goes. Now they make it in colors to match race car paint jobs. <sigh> It has generally been good quality duct tape, sometimes mil-spec grade, but surely not always. Back when I wrenched on race cars (Trans-Am and Can-Am), we just used more or less standard duct tape and it worked just fine up to about 150 MPH.
Having said all that, one thing missing that I would put in similar range of Gorilla Tape, a bit less adhesion, but clean removal, not as bulky/thick, is so-called Nuclear Duct tape. Love the stuff and it is standard for my client SHTF kits. NOT Cheap!
