Leather they are not, and hairspray was used, but I tend to grip my bars excessively and wanted to be sure there would be no slippage. I'm sure it would work pretty well in securing leather grips too though, well maybe until the sticky gives up the ghost.
It's more that leather stretches with repetitive twisting over time, and that it's not tape – so hard to get really tight to start with.
