If the refinisher is any kind of pro...they should know that Awlgrip will stand behind the product, check it to see if there was a defect, and provide free technical suport to both of you to find out what went wrong.
I'd suspect some kind of contamination or application issue but I'm sure ten minutes on the phone to Awlgrip can get you a professional answer, or the information on how to make the diagnosis. Odds are they will ask you to send in some of the blisters for testing.
