I first encountered it in shop class in jr high, and found it again at my corner deli/convenience store recently, and picked some up to try at work (I work in a sound rental shop for concerts and theatre we spend most days handling LOTS of very, very dirty speaker and mic cables!). Haven’t used Fast Orange, but some thoughts on other products mentioned above, and one not:ġ)Goop is pretty awesome, although it is definitely, well, goopy.
