On the night of Feb3,2021 I had a flat tire. I used Fixaflat. It worked. I drove successfully from Hickam AFB to my home in Moanaloa Valley. Next morning tire was still inflated. I called Firestone dealer where I purchased the tire for an appointment to get it repaired. They said since I used Fixaflat, they would not repair it and my only option was to purchase a new tire. I drove to Lex Brodie in Aiea. They repaired it, inflated all my tires to 35psi, and the best part- NO CHARGE. I will never do business with Firestone again and take both my wife's and my car to Lex Brodie from now on. Good bye Firestone at Ft Shafter.
