I have some old epoxy primer. I used some the other day. I wanted to test if it had cured properly. I wiped it down with some lacquer thinner and it started coming off. Should lacquer thinner cut cured epoxy primer?

Not if by epoxy, you mean hardened.

I didn't understand the comment E-tek. I have some fresh epoxy primer and after 3 weeks it will still rub off with lacquer thinner. Kevin Tetz responded to me on another forum and said it was just the nature of the material. So that appears to be the case...
