I guess I'm weird..I like Proseal
Best stuff ever invented! I use it for a lot more than just fuel tanks, But then again I have worked with the stuff frequently for the last 40 years in heavy jet overhaul. My day job is managing KC-10 refueling tanker depot maintenance, and this beast carries over 350,000 pounds of fuel , and all of those fuel cells, integral and bladders require extensive leak checks, deseal-reseal preventative maintenance. Pressurized aircraft structure is also completely assembled with with Proseal in every joint to seal it up. Lets just say we have a bunch of it! I love the smell of Proseal in the morning !!
