Ken,

Talk to Wiz when he finishes up at the North Americans this week. He has done it lots of times (and does a beautiful job, BTW). Biggie also knows. If I needed it done, I would see if I could get Wiz to do it. Before you do anything, make sure it is not just gelcoat cracks (fairly common) and that something really needs to be done that requires removal of the decks.
