Replacement Hardener for a discontinued Belzona "Fluid Metal" product

[brstanier]

Hi - Can anyone suggest a possible source of Belzona Molecular "Fluid Metal" hardener system compatible with the now discontinued product Code 619? Although rather old I have a decent stock of the Base component Product Code 619 but have completely run out of the Solidifier component Product Code 722. Failing a Belzona product has anyone tried using alternative varieties hardener systems perhaps from other suppliers which might be currently available in small quantities? The use in a non critical, low stress cosmetic application where it would be rather helpful to be able to use existing stock of what appears to be perfectly good if old stock material.
All suggestions and helful advice would be most welcomed
