Need a vinegar rub for this??
I don't think so. That looks pretty good to me. I'd only rub it if it got a different colored mold. If you leave the PR on there it will protect it from all the others.
How are you storing that cheese right now? You must be keeping the humidity up to get that nice PR growth.
BTW, I'd be careful with vinegar. I've heard of people ending up with strong vinegar flavor in their cheese.
