I bought my boat from out of state and it still has the name of the city, state(Manistee, MI) painted on the side of the boat. I've heard that EZ off oven cleaner works to remove paint from the gelcoat, but does it do any damage? also, what are the chances that I can still see the 'shadow' of the name after I've done it? I'd prefer to just leave it on if that is the case. also, need to remove the old registration numbers and apply new OH numbers. any advice for removing these? these are stickers, not painted on. thanks for any advice.
