Totally up to you which way you go. They both seem to have there advantages. I found doing it dry was the best for me doing it as Pinsanity has said. As you can see in the second picture I was able to stand back and rest to check the progress. If you do it dry just take your time and make sure its lined up before you start! Notice the clamp and transformer holding everything in place. Good luck with whichever method you choose.
