Liquid Electrical Tape - Good or Bad

[K1RCT]

I've used it in an Industrial setting. Not worth the expense. Messy to apply, messy cleanup if you have to remove it. It does not come off clean. Better to use fusion tape (3M, there are others).
Better to seal even to uneven surfaces like coax to connector. Some say you don't have to use Electrical Tape over the fusion tape but the Standard in Industry is to cover your fused tape with electrical tape.
