Old Glue Rejuvenation Question

[nwobhm]

Modern glues can be reactivated. My experience is specific to certain types of rubber cement used it the manufacture of air supported buildings.

We used Toluol and MEK to reactivate the adhesives before final assembly. The adhesive would go from rock hard to a syrup consistancy within seconds if hit with a wet rag of chemical.

If I were going to try this, Toluol would be my first choice. It's been around a very long time and was likely used in the original production adhesives. Depending on your location it may be difficult to find as well as expensive.
