I just located a limited supply of the 3MFeathering Disk Adhesive Type II in 5 fl oz tubes that I am offering for $17.00 per tube, plus shipping.
I can get two of these in a USPS small flat rate box or 4 if I take them out of their boxes. That would make shipping $5.35.

This is a low tack adhesive designed for adhering abrasive disks to disk grinders. The abrasive disk can be taken off and a new disk installed, then, later, the old disk reinstalled. A real convenience and money saver.
