I consider a gig successful if at the end of the day I’m able to pocket a full roll of Gorilla and a handful of assorted BNC/turnarounds.
(edit)
I’ll also add that for a very short time I pitched 3M transparent duct tape at a major trade show - fresh off the roll it was nice but after being used for a few days (in one case, holding down unglued linoleum to hardwood at a threshold )… dried up it was total shit.
