I had no wrapping experience at all either and I have to say that it turned out really well.. I was amazed with myself.
I just took off the trims using my hands. Start from a corner and gently pry towards you with your hands. (read diy for taking off the trims). when you are wrapping and need to do the corners, heat the vinyl and pinch it and bring it over to the back. If you want, I can post some pics for you tomorrow to see the finished product from a guy who had no wrapping experience before this one lol
