I did have a tin of new finish ? ( the orange tin) that I picked up very cheap go bad. (it was no big loss) It separated and would not mix at all. I only used it on my moms car. The new Autopia stuff ( BF & Pinnacle) is much better and I want to keep it useful for a while. I did put it in a baggie. I used very little this week during the winter prep top coat. Thanks for the answers so far !
