Tractor supply, has it, just be sure to get the correct one, there are 2, old kubota, and new kubota orange. they do not have the Dark gray, and none of the other grays they have even come close.. I wound up going to the dealer for an $11 can for that, but use the Van Sickel for the orange. Of course assuming your Kubota uses the Dark Gray, the older ones used a more blue color for the lower contrasting color. I have seen some say the Autumn Crush Valspar I think, at Lowes is a pretty good match. I havent tried it.
