coredump4 Posted October 22, 2014 Share Posted October 22, 2014 Hi, I'm getting ready to apply OC 2.0 to a family member's vehicle this weekend. I have roughly half of a syringe left over from 2012, and I can see the OC 2.0 has yellowed slightly in that time. Am I correct to assume I shouldn't use the remainder of this syringe? How long can I expect unused OC2.0 to last? And finally, what'd be the best way to store unused product to ensure longevity? thanks! Link to comment Share on other sites More sharing options...
