I don't know how much the paint cans are online, but just for reference, the one I bought to color test when I painted my glovebox lid cost $17 for 8.6 oz (looks like a standard can)
It's a bit expensive, but it's not enamel, it's the real Urethane paint.
But, it still will not harden like two stage sprayed out of paint gun....BUT, he told me that they sell it in a can that has the hardener in a "bladder" that you break and you have only a certain amount of time to spray it on.
That would harden a lot better than the Colormatch paint, but if you plan the sand it down and redo it soon it may not matter to you.
