I can never seem to get the lid off aquaseal once opened. I’ve started using a needle or a bodkin and punch a hole in the tube and squeeze out some of the aquaseal for repairs and then when I’m done, the small hole reseals itself after it dries and sets up. I can do this quite a few times before I have to throw the tube away. I agree, if aquaseal wasn’t such a good product, I wouldn’t buy it for all the reasons everyone has stated.
