Copper Clad Wire

Have a 100ft or so of that cable lying around. So I used it in a harness I built. Starter to relay,relay to fuse box. Where ever 10GA was called for. And for all the extra grounds I put in. But I made sure to cover it with heat shielding or split loom and secured it good because that insulation seems rather soft to me. Think it will last?

no...
