Over 2 years ago I purchased a bottle of Uno and 1 yellow pad to fix my wife's black car. After reading more I realized one pad wasn't going to cut it... anyway I never used the uno. It has sat for 2 years in garage exposed to temp changes and possible freezes. At this point is it still good? It is a milky white color and is very liquidy... I still use the HD poxy that has been treated exactly the same. Thanks for your help.
