My rule of thumb is, always try your best to do something as perfect as you can, you should at least wind up with something pretty good. don't torture yourself, that's really not that bad. I can't honestly say that I wouldn't redo it if it was mine, maybe, how much does it really bother you? I could see leaving it too, could always revisit it later, after it's fully cured. Like chuck said, even mass production ones can be off a little too. You really won't notice that, well, YOU will but no one else will; )
