Thanks.
Holy crap. Those are decent prices, but then it's $10 to ship. And how close is the match? And then you have to wait.
I drive 20 minutes out to Sherwin Williams Automotive (the "Automotive" part is important), and have them mix me up a can or two while I wait. I think it comes out to about the same, and then I can drive home and start using it immediately.
They also have the 2k clearcoat which is what you'll need if you want a factory-hard clear. It's in a can with a capsule of hardener inside that you puncture with a button on the bottom and when you mix it up, you have 48 hours to use it before it hardens in the can. Great stuff though. Just make sure you have a big enough job that you don't waste most of it.
