rdvt4me Posted June 22, 2016 Share Posted June 22, 2016 I got a tube of Opti-coat 2.0 3 1/2 years ago and used it on my wifes new car. We have replaced that car with a new one. I still have the tube of Opti-coat 2.0 left. There is about 20 ML in the tube. Is is still good to use on a new vehicle? Link to comment Share on other sites More sharing options...
