I did it today!
Great timing for your post. I just put a new vinyl trim on the stern of my 2002 B361 today. I ordered the vinyl from Beneteau (about $90). As others have said, it is a bitch to get it on. It was 85 degrees here in Chattanooga today so I went for it. In preparation, a couple of seeks ago I had "mounted" the vinyl on two 8-foot 1 x 4s to try to straighten it out. It helped some. I also used a hair dryer/heat gun. The thing that seemed to help the most was soap and a small crowbar. At any rate, I got it done, but will probably be sore for a week. :dance:
Also, after I finished, there were lots of black marks from shipping and from the rubber mallet I used, so I wiped the vinyl with MEK (very lightly)! It looks fabulous. The boat looks brand new, since I had the hull buffed last month.
Go for it, and you will save a month's membership at the gym.
