I would have to agree with Usjdmtuner, can't go wrong with Menzerna and 3M...but it's practice/trial and error that will get you the results your after.
I tried the XMT line before, it's okay but I would consider it to be a beginers line..oh wait that's what your asking lol...then it's fine

Thing with XMT line up is that it's meant for machines such as
PC, basically all DA machines you'll be able to use the XMT line...but I wasen't really satisfied with the end results..once you go Menzerna, you wont go back to any other product
