I have 2 original gallons of DCU 2001 Concept Clear in a factory sealed PPG case that has been stored indoors, in my possession since 2001. This clear is the real deal. If you are looking at this listing, you know what this is. The box is still factory sealed. This clear by many, is the best there ever was. Ask your painter, hot rod shop, or do your own research. I seriously doubt there is another in existence. No returns on this item, but I can guarantee this case has never been opened, and the cans are as they were when produced! Feel free to ask any questions. I also have another unopened case of DP402 avail on another auction.
