Anyone tried POR-15 to permanently stop rust.

I have used it on all my projects and still do. Through the years it's been 10 cars and 6 trucks. Just used it to treat the inside of my Norton Commando fuel tank. Good stuff.

Any evidence of it flaking off? I used the Kreem system to clean and coat the tank on my FZR600 but I have doubts that the "rubber bladder" coating will last forever. I am especially concerned that somehow the coating will get damaged and the tank will rust again...

None. I can tell you that POR 15 is the tool of choice for tank coatings now that we have to deal with ethanol. Apparently all the other coatings are affected by Ethanol over time. Some quicker than others. With the Norton, those were primarily manufactured with fiberglass tanks then coated. The ethanol is raising havoc with that coating and the fiberglass resins. The rebuild of my Norton constituted the use of a custom built metal tank and the builders pick was and is POR 15 for it and all the others he repairs and/or builds.
