Thanks for reply Foolish, I ended up removeing my rubber and tape and wraped aluminium tape around it , than put auto spiral around it, I have 4 flights with it , with no issues. For future reference, anybody that gets there plug wire frayed, wrap aluminium tape around it and you will be ok.
A problem that can often develop when the shield gets worn away is that the insulation also gets worn some too. When this happens, the worn plug cable can cause the spark voltage to arc through the cable. This effectively removes or shunts the spark voltage from the plug causing hard starting and / or rough, intermittnet engine running. When a plug lead gets worn, it should be replaced in my opinion. Also, that shiny shielding is not stainless .... it is just tinned copper and wears away very quickly when it contacts a sharp fiberglass cowl edge.
Your aluminum tape bandage may help prevent interference to your radio but will do nothing to prevent arcing inside your cable.
