I have a two reel stainless steel tank that has the plastic lid. I don't use it that much and I don't leave it on the tank when not in use. I just used it to develop a couple of 35mm reels and it leaked pretty badly. I ended up wrapping it in a towel to stop the slop but I'd like to figure out how to stop it from happening before I buy a new tank and cap. Has anyone fixed this issue with their stainless steel tank and plastic lid combo?
