I wrote about this a few weeks ago. You can still get the real thing - Floquil Oxide Red - if that is the match you need.

And yes, they are unopened bottles and they sell at the last retail price that Floquil sold at.

I opened a bottle I bought recently from them a few days ago and the paint was fine.
