I was speaking to a local distributer which is Stevens International.
They informed me that the problem with Gunze is the same problem
that Tamiya had a fue years ago with the labeling on the bottles.
For the amount of business that they do in the US it may not be
in there interest to relabel the product. This is what I was told I when looking for the liquid putty in the Gunze /Mr. Hobby line. How true this is i don't know.
But Stevens is a pretty large distributor and they have been correct in the past. So ordering over seas maybe your only option for now.
