Hi, welcome to Sailnet. I'm sure you know that the fluid in the blisters is acidic so wear eye protection when opening them up. The main thing is to get to good clean glass, so grind them or use a dremel depending on size and let them completely dry out. If you can direct a fan at the bottom it will aid in drying, you can also use a heater if you are inside or if it is tented and the weather is cold or humid.
