Heh. Didn't even occur to me that his hulls might have worn down from the original shape. That being the case I would definately use some thickened epoxy to build it up. My reason for pre-saturating the first layer of fiberglass cloth was to keep epoxy from running down the sides of the hulls and becoming a general pain. If he's got the thickened epoxy there already, however, then that'd serve the same purpose and he could put down the dry fiberglass cloth over it.
