I am assuming that you Opti-coated your car and the remainder was kept in the glass container. The remaining product is what went bad. correct???
The product is curing and it can't be saved. Most coating products are not meant to be in storage once the original seal has been opened. That's why they sell them in small quantity containers.
What is absolute control???? Having the means and the abilities to exercise it at will but....chooses not to.
