So, got some pretty neat stuff to try, Sugru. It's a moldable silicon that hardens overnight. I used the first batch to fix a fraying Apple USB cord. It worked great for this and is better than what I have tried before, liquid electrical tape.
However, I also used it to put some feet on a granite tile to use for sharpening...not 'non-skid'...so, don't use it for non-slip feet.
Not sure what else to do with it...and I have lots of it....and it has a limited shelf life.
