Not long ago it was rubber and friction tape, I think soon to be a dead art.
Many people including myself have moved on to insulated lugs for most stuff, like say in a can. I still kearny service's.
Also, ironicly, did some CuAl kerney's today for a 200a service. Noalox, 3M slicing putty (1/4" thick), and friction tape.
IMO vinyl or plastic tape exposed to UV and weather breakes down over time. Good friction tape is getting harder to find though.
