    The two bikes in my garage I ride do not have liners.
    I do however have two decent Skunk tanks that have peeling liners that will need removed somehow.
    When I figure out how to make this happen I wont put liners back in em.

      With the peeling liners, the nuts and vinegar method can work. I've also been advised that BBs work as well.

      However, the place that I took my tank to said that to absolutely guarantee no old liner is left in the tank is to bake it.

      The only problem with that is you have no choice but to repaint the tank. It not only gets the old liner out, it gets everything out and off the tank. You'll be left with bare metal and a fresh canvas.

        I've spent a lot of time derusting/lining tanks and frankly, I'm still not 100% clear on what's best to do.

        I do know that if there is lots of rust the metal will be thin so a liner is recommended. Contrary to what many of the liner companies (like Por-15 and Caswell's) tell you, I strongly believe it's best to derust to the best of your ability before sealing.

        As for how to derust, I'm not sure what's the best way. I've used phosphoric acid and aquarium rocks in the past and that works well as long as you rotate the tank a lot and make sure to shake the crap out of the tank often to scrub off the chalky phosphate layer that forms on the metal. Even after a good deal of time soaking it's hard to tell if all the rust is removed from the pits in the metal.

        I've also used Evaporust and that stuff is great (maybe the best solution). It turns the metal dark if you leave it for a long time though so that might not be so cool for some (only will be an issue on a heavily rusted tank).

        Electrolysis also turns the metal dark and I've read one tidbit that references it as an "ionized" coating, that should be scrubbed off (maybe with those aquarium rocks).

        One other thing I do know is nuts/bolts/screws/nails/etc. don't scrub the metal half as good as aquarium rocks, but they are easier to get out of the tank when you are sick of shaking it.

        As for liner materials, it's hard to fault POR-15. As long as the rust is removed to the best of your ability, and the metal is physically scrubbed clean, I think it's save to use without fear of peeling. At least I hope it is since I've used it three different times so far.

          Neither tank on my '79 GS1000E or '82 GS1100E is lined, I do have a "spare" '79 GS1000E tank that will be lined because it does have
          a leak at the left front mounting bracket.
