Here are a few things I learned in the process.

-I thought I would want the thinnest paint scraper around ,but I found out that you had no control over it and it ended up causing more trouble, so we upgraded to a heavy knife with a pretty thick blade. It work very well and the cleanest areas are the knife areas.
-We worked as a team to do it, after I got the knife under the deck I would slowly work it down and my friend would use the butter knife to hold the deck up to make sure I stayed between the deck and the actual hull.
