I mount and balance my own tires so just need a sharpie arrow on the barrel at the repair area before paint and tape on top after paint so I know where the repair is myself.

Grinding a key into a repair is always good. I'd still at least dimple each end and put stuff wire in there, sprung or wedged to make a bridge from on side to the other. I put stakes, hoops, bridges, etc. in all fill repairs except TIG or MIG as they will melt the wire making it useless.
