T-cut (and the like) any good?

I've got some minor scratches on the door of my Micra and was thinking as I'm just about to sell it I ought to try and get them out. I've never tried something like t-cut before, does it actually work?

I'm going to have to look into that, I've managed to get some annoying scratches on my new car (a lot larger car and having power steering is a bad combo).
