It seemed useful to post this general information here rather than bury it in my build thread.

Today I had a conversation with Lars, Oratex Tech Support, Alaska. One question was the shelf life of the two component glue listed in their catalog. The instructions for this two component system said to mix the complete contents of the bottles. The factory learned builders were mixing small batches and the lawyers went nuts worrying about inaccurate measurements and liability issues. Now, the glue is only available pre-mixed and the catalog is out of date.

This news led to the obvious question of the shelf life of the pre-mixed glue. If you keep the bottles at a stable temperature and out of the sun, the glue is good for one year. Widely varying temperatures or exposure to sunlight can reduce this to three months.
