I asked this question earlier, but did not mention it was enamel. Got a lot of answers, but still looking for a solution.
Thanks

IMHO, if the enamel is in good shape, learn to live with it, and count your blessings that you have a 'real' cast-iron tub, as opposed to a modern steel or plastic one. Others on here will disagree, but I have never personally seen a field-refinished tub that looked 'right', and the consensus seems to be that under daily use, the refinish doesn't last very long. And unless you are a rich person, you don't get cast iron any more.
If you simply can't stand the green under any circumstances, I'd go with a tub liner, assuming you can take the tub being slightly smaller. (although I understand they are not nearly as bad as they used to be, that way.)
