As for your second repair when he pulled the patch off he had to buff it to get a good clean spot making that rubber on the inside a little thin.

The main question is - whether repetitive buffing at the same surface doesn't harm it make it weaker. I am not specialist but I'd rather following the law and making the best repair rather than wondering and worrying. in my country anyways mushroom repair is the only one that allowed and I'm saying it after look-up.
