    tank liner sealer ID

    Hey all. Can anyone identify the liner/sealer in the attached pic. I am going clean and reseal the tank. Would like to know what WAS / IS in it before I begin. The pieces in the pic came out relatively easy but need to do a lot of prep before resealing with Caswell 2 part sealer. Thank you.

    Looks like kreem; not the most popular for obvious reasons

      That's what I thought as well. Thanks for your opinion posplayr

        Classic example of not enough prep before coating. There was rust under the liner

          Yep there was and is rust under the sealer. This is from the tank of my 84 Canadian Pop up Katana. Only 200 of these beauties produced so I want to do it right

            Prep, lots of prep and watch for flash rusting after rinsing

              When I did my gas tank, it was dipped in Acid magic. It would flash rust before you could get the tank dry. You can't get rid of all the rust. The Por-15 and I assume caswell, cover the rust and prevent air from getting to it. This arrests the oxidation(rusting).
              I assume the Kreem is much more permeable, and does not create this barrier.

                A rinse with water is the mistake.

                Rinse with acetone or MEK and flash rusting is not a problem.

                I would rather trust my bike to a technician that reads the service manual than some backyardigan that THINKS HE KNOWS how to fix things.

                  I rinsed with por-15 tank sealer and the flash rust was not a problem. It gives bite.
