The freeze leak was difficult to fix with a caulking gun as I didn't know how to depressurize the low pressure side of my heat pump. However, after leak testing my oven's evaporative coils, the leak stopped within 30 minutes. I rate this product 5 stars because I was only able to fix 70% of the freeze leak in my air conditioner and it still worked to stop the leak.
