My PSO indicated that when he does plug work on a ball, he always resurfaces the ball as part of the final step of the process to make sure the finish is even all the way around. He always warns customers that the ball may seem to hook less, or go longer, at first. Once it has a handful of games on it and gets a track back on it, the reaction should return to what it was before the plug work.
That being said, with my high end solids I rarely ever hit them with a pad. I just clean them immediately after every session and that keeps them reacting great. Really, the only time I use abralon or siaair is when I am trying a completely different surface on a ball. Otherwise, I just clean and go.
